The asymmetric unit of the title compound, C11H9N3O, contains two independent and nearly identical mol­ecules (A and B). Mol­ecule A can be transformed to B using a rotation of approximately 85° around the [111] direction. Each A mol­ecule is connected to three B mol­ecules via N—H⋯N and N—H⋯O hydrogen bonds and vice versa. Centrosymmetric­ally related mol­ecules of the same residue form ππ inter­actions with centroid–centroid distances of 4.326 (1) and 3.826 (1) Å for the benzene rings of mol­ecules A and B, respectively.

Comment top

Amino(2-alkyl-3-oxo-2,3-dihydro-1H-isoindol-1-ylidene)acetonitriles are readily obtained in a three-component reaction between 2-carboxybenzaldehyde (2-formylbenzoic acid), aliphatic amines and cyanide in acidic medium. While steric hindrance is a decisive factor and the reaction fails for α-branched primary amines such as isopropylamine, all tested unbranched primary amines give the desired products. Consequently, the highest yield of 53% is found for the preparation of the title compound, in which unfavorable steric interactions are reduced to a minimum. Despite the fact that this compound had been obtained as the prototype example of the series, the determination of its crystal structure was hampered by twinning of the crystals. Compared to the N-benzyl derivative described earlier (Opatz & Ferenc, 2004), the exocyclic aminoacetonitrile unit is even less twisted against the plane of the bicyclic π-system (5.0 (1)° and 1.7 (2)°) (Fig. 1). Furthermore, the compound forms a hydrogen bonded network, in which both exocyclic nitrogen atoms as well as the oxygen atom act as acceptors and the NH2 group is the double donor. Centrosymetrically related molecules of the same residue form π-π-interactions. The distances between the centroids are 4.326 (1)Å and 3.826 (1)Å for the rings C1–C6 of A and B respectively (Fig. 2).

Experimental top

The preparation was carried out as described in the procedure reported by Opatz and Ferenc (2004). The (Z)-isomer was obtained by recrystallization of the isomeric mixture from hexanes/ethyl acetate. Single crystals suitable for X-ray crystallography were grown by evaporation from a CH2Cl2 solution.

Refinement top

Hydrogen atoms attached to carbons were placed at calculated positions with C—H = 0.95 Å (aromatic) or 0.98–0.99 Å (sp3 C-atom). Hydrogen atoms attached to N were located in difference Fourier maps. All H atoms were refined in the riding-model approximation with isotropic displacement parameters (set at 1.2–1.5 times of the Ueq of the parent atom). The crystal used for data collection was twinned. Using the twin matrix 0 - 1 0, -1 0 0, 0 0 - 1 with BSAF 0.468 (1) the structure refinement was succesful.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

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.
