Crystal structure of 3-amino-1-(4-chloro-phen-yl)-1H-benzo[f]chromene-2-carbo-nitrile.

ABSTRACT: In the title compound, C20H13ClN2O, the chloro-benzene ring is almost perpendicular to the mean plane of the naphthalene ring system, making a dihedral angle of 81.26 (8)°. The 4H-pyran ring fused with the naphthalene ring system has a flattened boat conformation. In the crystal, N-H⋯N hydrogen bonds generate chains along the b-axis direction. Further N-H⋯N hydrogen bonds link these chains into sheets parallel to (010). The crystal packing also features C-H⋯π inter-actions. The crystal studied was an inversion twin with a 0.557 (16):0.443 (16) domain ratio.

Crystal structure of 4-(2-azido-phen-yl)-5-benzoyl-2-(1H-indol-3-yl)-1H-pyrrole-3-carbo-nitrile.

Project description:In the title compound, C26H16N6O, the dihedral angles between the central pyrrole ring and the pendant indole ring system (r.m.s. deviation = 0.027 Å) and the azide-bearing benzene ring are 37.56 (8) and 51.62 (11)°, respectively. The azide group is almost coplanar with its attached benzene ring [C-C-N-N = 3.8 (3)°]. The benzoyl benzene ring is disordered over two orientations twisted with respect to each other by 9.29 (8)° in a 0.514 (2):0.486 (2) ratio. In the crystal, inversion dimers linked by pairs of Np-H⋯O (p = pyrrole) hydrogen bonds generate R 2 (2)(10) loops. A second inversion dimer arises from a pair of Ni-H⋯Nc (i = indole and c = cyanide) hydrogen bonds, which generates an R 2 (2)(16) loop. Together, the hydrogen bonds lead to [011] chains in the crystal.
