The structure of a third pseudopolymorphic hydrate of brucine, brucine–water (1/2) [systematic name: 2,3-dimethoxy­strychnidin-10-one–water (1/2)], C23H26N2O4·2H2O, has been determined at 130 K. The asymmetric unit comprises two independent brucine mol­ecules and four water mol­ecules of solvation. The four water mol­ecules form uncommon cyclic hydrogen-bonded homomolecular R44(8) tetra­mer rings, which then form primary hydrogen-bonded chain substructures extending down the 21 screw axis in the unit cell. The two brucine mol­ecules are linked peripherally to these substructures by either single O—H...Nbrucine or asymmetric three-centre O—H...Obrucine hydrogen bonds.

Comment top

The common crystalline form of the alkaloid brucine is a tetrahydrate [brucine–water (1/4)], and we have completed the structure determination of this and another pseudopolymorphic hydrate, brucine–water (1/5.25), obtained from the attempted preparation of a brucine adduct with urea (Smith et al., 2006a). Other crystallographically characterized brucine pseudopolymorphs include anhydrous brucine, brucine–acetone (1/1) and brucine–2-propanol–water (1/1/2) (Bialońska & Ciunik, 2004a), and brucine–ethanol–water (1/1/2) (Glover et al., 1985). The 2-propanol–water and ethanol–water solvates are isomorphous.

In a number of these solvate structures, as well as in the proton-transfer compounds of brucine, it has been recognized (Gould & Walkinshaw, 1984; Bialońska & Ciunik, 2004b; Smith et al., 2006a,b) that the brucine species form regular undulating parallel or antiparallel host sheet substructures, accommodating the guest molecules in the interstitial cavities. Thus, molecules of solvation are similarly incorporated and associated through hydrogen bonding. In the orthorhombic P212121 or monoclinic P21 examples, the presence of a ca 12.5 Å unit-cell repeat along a crystallographic 21 screw axis was reasonably indicative of this characteristic substructure, e.g. in brucine–2-propanol–water (1/1/2) (12.37 Å; Bialońska & Ciunik, 2004a) and brucine–ethanol–water (1/1/2) (12.34 Å; Glover et al., 1985) (both P212121), or in the proton-transfer example brucinium-D-glucuronate (12.7 Å; P21; Dijksma et al., 1998). In examples where the ca 12.5 Å/P21 cell parameter/space group combination is not found, the characteristic structuring is usually absent, e.g. brucine–acetone (1/1) (7.14 Å; P21) in the present set of brucine solvates (see Table 1); brucine–water (1/4) (11.53 Å; P212121), in which the structure is present, is the exception. On the basis of this generalization, the structure of the monoclinic dihydrate, brucine–water (1/2), (I), obtained from the attempted preparation of a brucine–diethanolamine adduct in 95% ethanol, was not expected to have the structuring (with b ca 7.45 Å; P21). This structuring was in fact found, distinguishing the structure from those of brucine–water (1/4) and brucine–water (1/5.25) (Smith et al., 2006a).

In (I), the asymmetric unit comprises two independent brucine molecules and four water molecules of solvation. The two brucine molecules (A and B) (Fig. 1) have the overall Cahn–Ingold–Prelog absolute configuration [C7(R), C8(S), C12(S), C13(R), C14(R), C16(S)] as found in strychnine (Peerdeman, 1956). Because of the rigid nature of the brucine molecular cage, both molecules, as expected, are conformationally identical, including the methoxy substituents at C2 and C3, which in all brucine structures lie essentially in the plane of the benzene ring. In the efflorescent brucine–water (1/5.25) structure, the asymmetric unit also comprises two independent brucine molecules together with 10.5 molecules of solvent water, some of these having split-occupancy sites. However, unlike this structure, in which one set of brucine molecules form the common undulating sheet substructure, in (I) there is no such structuring. Instead, the water molecules dominate the structure assembly, forming uncommon cyclic hydrogen-bonded tetramer units (graph set R44; Etter et al., 1990; Bernstein et al., 1995) (Figs. 2 and 3). These are analogous to the cyclic water pentamer units found in the structure of brucinium L-glycerate 4.75-hydrate (Białońska et al., 2005). In (I), O—H···O—H···O associations (O4W—H42W···O3Wi; symmetry code as in Table 2) link the tetramers into chain structures which form down the 21 screw axis in the unit cell (Fig. 2).

The brucine molecules are linked peripherally to these water structures by hydrogen bonds; there is a single linear interaction with a nitrogen acceptor of a B molecule (O2W—H22W···N19Bi), as well as an asymmetric three-centred interaction with the carbonyl O acceptor of an A molecule [O2W—H12W···O25A and O3Wvii—H32W···O25A; symmetry code: (vii) x + 1, y + 1/2, −z]. The second carbonyl O atom of molecule B (O25B) and atom N19A of molecule A are unassociated except for some weak C—H···O and C—H···N interactions. Unlike the structures of both of the other brucine hydrates (Smith et al., 2006a) there are no water-O-H···O(methoxy) interactions in (I).

It can be assumed that formation of different pseudopolymorphic solvates of brucine depends not only upon solvent composition (Bernstein, 1987; Kumar et al., 1999) but, in the case of the pure hydrates, also upon the presence of additional non-incorporated but structure-influencing solute components, e.g. diethanolamine in the case of (I) and urea in brucine–water (1/5.25).

Experimental top

Brucine dihydrate (I) was obtained from the attempted preparation of a 1:1 brucine–diethanolamine adduct by refluxing 0.1 mmol quantities of brucine tetrahydrate and diethanolamine in 40 ml of 50% ethanol–water for 10 min. Colourless prismatic crystals were obtained after total room-temperature evaporation of the solvent.

Refinement top

H atoms potentially involved in hydrogen-bonding interactions were generally located by difference Fourier methods. Some of the H atoms on the water molecules could not be located and were included in the refinement at calculated sites dictated by the assumed hydrogen-bonding geometry, and their positional and isotropic displacement parameters were refined. However, because of the poor reflection–parameter ratio, these were fixed in the final refinement cycles. Brucine H atoms were included at calculated positions [C—H (aromatic) = 0.95 Å and C—H (aliphatic) = 0.98–1.00 Å] and treated as riding, with Uiso(H) values of 1.2Ueq(C). The absolute configuration determined for the parent strychnine (Peerdeman, 1956) was invoked. Friedel pairs were averaged for the data used in the 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.
