3-Amino-1-phenyl-1H-benzo[f]chromene-2-carbonitrile.

ABSTRACT: In the title compound, C20H14N2O, the phenyl ring is almost normal to the naphthalene ring system with a dihedral angle of 86.72?(9)°. The 4H-pyran ring fused with the naphthalene ring system has a boat conformation. In the crystal, mol-ecules are linked into a helical supra-molecular chain along the b axis via N-H?N hydrogen bonds. The chains are consolidated into a three-dimensional architecture by C-H?? inter-actions.

In the title compound, C20H14N2O, the phenyl ring is almost normal to the naphthalene ring system with a dihedral angle of 86.72 (9)°. The 4H-pyran ring fused with the naphthalene ring system has a boat conformation. In the crystal, mol-ecules are linked into a helical supra-molecular chain along the b axis via N-H⋯N hydrogen bonds. The chains are consolidated into a three-dimensional architecture by C-H⋯π inter-actions. ...[more]

3-Amino-1-(4-fluoro-phen-yl)-7-meth-oxy-1H-benzo[f]chromene-2-carbonitrile.

Project description:In the title compound, C21H15FN2O2, the furan ring has a flattened half-chair conformation [the methine C atom lies 0.136?(2)?Å above the C5 plane which has an r.m.s. deviation of 0.0229?Å]. Overall, the 1H-benzo[f]chromene fused-ring system approximates a plane (r.m.s. deviation of the 14 non-H atoms = 0.049?Å). The fluoro-benzene ring is almost perpendicular to this plane [dihedral angle = 89.58?(8)°]. Zigzag supra-molecular tapes along the b axis are the most notable feature of the crystal packing. This arises through an alternating sequence of 12-membered {?HNC3N}2 and eight-membered {?HNCO}2 synthons. These are connected into a three-dimensional architecture by ?-? [inter-centroid distance for centrosymmetrically related fluoro-benzene rings = 3.5181?(10)?Å] and C-H?? inter-actions.

Project description:The asymmetric unit of the 5:3 title co-crystal of 2-amino-4-phenyl-5,6-dihydro-benzo[h]quinoline-3-carbonitrile and 3-amino-1-phenyl-9,10-dihydro-phenanthrene-2,4-dicarbonitrile, 0.625C(20)H(15)N(3).0.375C(22)H(15)N(3), has the atoms of the fused-ring system and those of the amino, cyano and phenyl substitutents overlapped.
