In the structure of the title 1:1 proton-transfer compound of brucine with 2-(2,4,6-trinitro­anilino)benzoic acid, C23H27N2O4+·C13H7N4O8·H2O, the brucinium cations form classic undulating ribbon substructures through overlapping head-to-tail inter­actions, while the anions and the three related partial solvent water mol­ecules (having occupancies of 0.73, 0.17 and 0.10) occupy the inter­stitial regions of the structure. The cations are linked to the anions directly through N—H...OCOO hydrogen bonds and indirectly by the three water mol­ecules, which form similar conjoint cyclic bridging units [graph set R24(8)] through O—H...OC=O and O—H...OCOO hydrogen bonds, giving a two-dimensional layered structure. Within the anion, intra­molecular N—H...OCOO and N—H...Onitro hydrogen bonds result in the benzoate and picrate rings being rotated slightly out of coplanarity [inter-ring dihedral angle = 32.50 (14)°]. This work provides another example of the mol­ecular selectivity of brucine in forming stable crystal structures, and also represents the first reported structure of any form of the guest compound 2-(2,4,6-tri­nitro­anil­ino)benzoic acid.

Comment top

Although brucine has been used largely for the resolution of certain chiral compounds (Wilen, 1972), it has proven utility in the formation of crystalline adducts and salts with achiral carboxylic acids. In particular, the benzoic acid analogues have provided a number of brucinium salt structures, many of which are solvated, e.g. benzoic acid (a trihydrate) (Białońska & Ciunik, 2006b), 3-nitrobenzoic acid (methanol monosolvate) (Oshikawa et al., 2002), 4-nitrobenzoic acid (isomorphous dihydrate and methanol monosolvate) (Białońska & Ciunik, 2007), 4-hydroxybenzoic acid (isopropyl alcohol monosolvate) (Sada et al., 1998), 3,5-dinitrobenzoic acid (trihydrate, methanol monosolvate and disolvate) (Białońska & Ciunik, 2007) and the anhydrous example with 5-nitrosalicylic acid (Smith, Wermuth, Healy & White, 2006). Three 1:1 salts are also known: with 5-nitrophthalic acid (a dihydrate) (Smith et al., 2005), isophthalic acid (a trihydrate) (Smith, Wermuth, Young & White, 2006) and 4,5-dichlorophthalic acid (anhydrous) (Smith et al., 2007a). However with these acids, formation is certainly a hit-or-miss process, the selectivity being dependent upon guest molecule compatibility with the interstitial cavities in the brucinium cation substructures which are present in a large number of brucine adduct and brucinium proton-transfer compounds (Gould & Walkinshaw, 1984; Dijksma et al., 1998; Oshikawa et al., 2002; Białońska & Ciunik, 2004; Smith, Wermuth, Healy & White, 2006). In these substructures, the brucine species form undulating ribbons comprising overlapping head-to-tail molecules, this host structure then accomodating the compatible guest molecule or molecules and interacting with them through hydrogen-bonding associations. This phenomenon accounts for the presence in many of the structures of various polar solvent molecules. It has also been noted that the two-molecule brucine repeat period will be ca 12.5 Å (the cell dimension) in the direction of a 21 screw axis, of which there is a high incidence among the small number of space groups into which brucine and its compounds and adducts fall (Smith, Wermuth, Healy & White, 2006).

The isomeric picraminobenzoic acids [2-, 3- and 4-(2,4,6-trinitroanilino)benzoic acid] were first synthesized by the reaction of the corresponding monoaminobenzoic acid with picryl chloride in 1911 (Crocker & Matthews, 1911). We have synthesized these three compounds using picrylsulfonic acid rather than picryl chloride, reporting the crystal structure of the para-isomer (Smith et al., 2007b). However, the uncompromising crystal morphology of the ortho- and meta-isomers precluded the structure determinations of these. The 1:1 stoichiometric reaction of 2-(2,4,6-trinitroanilino)benzoic acid with brucine in aqueous ethanol gave good crystals of the orange–red hydrated title salt, (I), and the structure is reported here. No suitable crystals resulted from the reactions of brucine with the meta- and para-isomers.

In (I), protonation has occurred, as expected, at N19 of the brucine cage (Fig. 1), the absolute configuration of the seven chiral centres of the brucinium cation being invoked (Peerdeman, 1956). These cations form the previously described undulating ribbon host substructures, which have a dimeric repeat period in (I) of 12.4407 (3) Å along the direction of propagation [a 21 screw axis, the a cell dimension] (Fig. 2). This value for the dimeric repeat in (I) is consistent with those for similarly structured brucine compounds (Gould & Walkinshaw, 1984; Smith, Wermuth, Healy & White, 2006). There is a molecule offset of ca 120° in the repeat unit of (I).

The monoanion and the three associated partial solvent water molecules [O1W (site occupancy factor 0.73), O2W (site occupancy factor 0.17) and O3W (site occupancy factor 0.10)] occupy the interstitial volumes between the brucine substructures and are hydrogen-bonded to them. The brucinium cations form an N+—H···O hydrogen bond with a carboxyl O acceptor of the anion, while the water linkages are unusual, the three partial molecules forming a set of similar conjoint cyclic associations [graph set R24(8); see Bernstein et al. (1995) for graph-set notation] involving two O acceptor atoms (brucinium carbonyl atom O25 and carboxyl atom O3A of the anion) (Table 1) (see Fig. 2), giving a two-dimensional structure which forms layers down the c cell direction (Fig. 3). Within the anion, intramolecular N—H···Ocarboxyl and O—H···Onitro hydrogen bonds result in moderate rotation of the benzoate and picrate ring systems out of coplanarity [inter-ring dihedral angle = 32.50 (14)°]. The ortho-carboxyl group of the benzoate ring is rotated slightly out of the plane of the benzene ring [torsion angle C1A—C2A—C22A—O3A = 159.4 (3)°], while the two ortho-related nitro groups are similarly non-coplanar with the picrate ring [torsion angles C11A—C21A—N21A—O22A = 151.7 (3)° and C11A—C61A—N61A—O61A = -165.2 (3)°]. The less sterically compromised para-nitro group is essentially coplanar with the picrate ring [torsion angle C31A—C41A—N41A—O42A = -177.8 (3)°]. One of the O atoms of the ortho-related nitro group at C21A is involved, not unexpectedly, in some short intramolecular non-bonded interactions [O21A···C1A = 2.852 (4) Å and O21A···N1A = 2.892 (4) Å].

The structure presented here provides another example of the molecular selectivity of brucine in forming stable complexes and is also the first reported structure of any form of the guest compound 2-(2,4,6-trinitroanilino)benzoic acid.

Experimental top

Compound (I) was synthesized by heating together brucine tetrahydrate (1 mmol) and 2-(2,4,6-trinitroanilino)benzoic acid (o-picraminobenzoic acid) (1 mmol) in 50% ethanol–water (50 ml) under reflux for 10 min. After concentration to ca 30 ml, partial room-temperature evaporation of the hot-filtered solution gave short orange–red prisms of (I) (m.p. 475 K).

Refinement top

C-bound H atoms were included at calculated positions, with C—H = 0.93 (aromatic) or 0.96–0.98 Å (aliphatic), and treated as riding, with Uiso(H) = 1.2Ueq(C). The H atom of the brucinium N+—H group was located in a difference Fourier synthesis and its positional and isotropic displacement parameters were allowed to ride in the refinement. The occupancy of the three partial solvent water molecules were determined as 0.73 (O1W), 0.17 (O2W) and 0.10 (O3W) from peak heights, and the O atoms of the two minor-occupancy components were refined isotropically. All three partial water molecules were found to be associated with the same two O-atom acceptors, and the H atoms on these were derived geometrically and also allowed to ride in the refinement. The known absolute configuration of the parent strychnidin-10-one molecule (Peerdeman, 1956) was invoked and Friedel pairs were averaged for data used in the final cycles of refinement.

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell e.s.d.'s are taken into account in the estimation of distances, angles and torsion angles

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R-factors based on ALL data will be even larger.
