2-Amino-4-(4-bromophenyl)-6-methoxy-4H-benzo[h]chromene-3-carbonitrile
In the title compound, C21H15BrN2O2, the 14 non-H atoms of the 4H-benzo[h]chromene fused-ring system are approximately coplanar (r.m.s. deviation = 0.129 Å). Within this system, the 4H-pyran ring adopts a flattened half-chair conformation with the methine C atom lying 0.281 (4) Å above the plane of the remaining atoms (r.m.s. deviation = 0.0446 Å). The bromo-benzene ring is almost perpendicular...

In the title mol-ecule, C(21)H(15)FN(2)O(2), the dihedral angle between the fluoro-substituted benzene ring and the mean plane of the 4H-benzo[h]chromene ring system [maximum deviation = 0.109 (2) Å] is 83.35 (7)°. The pyran ring adopts a slight sofa conformation with the tertiary C(H) atom forming the flap. The meth-oxy group is slightly twisted from the attached benzene ring of the 4H-benzo[h...

The asymmetric unit of the title compound, C(18)H(17)ClN(2)O(2)·0.5H(2)O, contains two organic mol-ecules and one solvent water mol-ecule. In each organic mol-ecule, the cyclo-hexene ring adopts an envelope conformation with the C atom connecting the two methyl groups on the flap; the 4H-pyran ring is nearly planar [maximum deviation = 0.113 (3) Å in one mol-ecule and 0.089 (3) Å in the other m...

In the title compound, C21H16N2O2, the naphthalene fragment is twisted slightly, as indicated by the dihedral angle of 3.2 (2)° between the two six-membered rings. The pendant 4-meth-oxy-phenyl ring makes a dihedral angle of 86.08 (6)° with the central six-membered ring of the 4H-benzo[g]chromene ring system. In the crystal, mol-ecules are linked by pairs of N-H⋯N hydrogen bonds, forming invers...

In the title compound, C16H12N2O3, the chromene ring system is nearly planar [maximum deviation from the mean plane = 0.057 (1) Å], and is almost perpendicular to the benzene ring, with a dihedral angle of 85.29 (5)°. In the crystal, mol-ecules are linked by classical N-H⋯O, O-H⋯O and O-H⋯N hydrogen bonds, and weak C-H⋯O hydrogen bonds, forming a three-dimensional supra-molecular network. Furth...
