2,4-Diphenyl-4,5-dihydro-3H-pyrido[2,3-b][1,4]diazepine
The asymmetric unit of the title compound, C(20)H(17)N(3), contains two crystallographically independent mol-ecules (A and B). In mol-ecule A, the two benzene rings form dihedral angles of 74.12 (7) and 7.83 (7)° with the pyridine ring, while in mol-ecule B these angles are 77.48 (7) and 21.50 (7)°. The seven-membered heterocyclic ring adopts a boat conformation in both mol-ecules. In the cryst...
متن کاملEthyl 2-diethylamino-4-oxo-3,5-diphenyl-4,5-dihydro-3H-pyrrolo[3,2-d]pyrimidine-7-carboxylate
In the title compound, C(25)H(26)N(4)O(3), the two fused pyrrolo-[3,2-d]pyrimidine rings form a dihedral angle of 3.7 (2)°. The two substituent phenyl rings are twisted with respect to the pyrrole and pyrimidine rings, making dihedral angles of 57.2 (2) and 69.0 (2)°, respectively. The ethyl and eth-oxy groups are disordered over two positions; the site occupancies are 0.53 (1) and 0.47 (1) for...
متن کامل1,2-Dihydro-9H-carbazole-4(3H)-thione
The crystal structure of the title compound, C(12)H(11)NS, features parallel chains of alternating N-H⋯S hydrogen-bonded mirror-image conformers along [10[Formula: see text]]. The mol-ecular conformation is that of an envelope, with all of the framework atoms except one close to a mean plane (rms deviation 0.054 Å); one C atom of the cyclo-hexene-thione ring forms the envelope flap, which makes...
متن کامل3-Methyl-1,5-diphenyl-4,5-dihydro-1H-pyrazole
In the title compound, C16H16N2, the dihydro-pyrazole ring adopts a shallow envelope conformation, with the C atom bearing the phenyl group displaced by 0.298 (2) Å from the other atoms (r.m.s. deviation = 0.015 Å). The dihedral angles between the four near coplanar atoms of the central ring and the N- and C-bonded phenyl groups are 13.49 (13) and 82.22 (16)°, respectively.
