Crystal Structure of 7-(4-Fluorophenyl)-5,6,7,14-tetrahydroquinolino[4,3-b]-benzo[f]quinolin-6-one N,N-Dimethylformamide Solvate

Abstract

The crystal structure of 7-(4-fluorophenyl)-5,6,7,14-tetrahydroquinolino[4,3-b]benzo[f]-quinolin-6-one N,N-dimethylformamide solvate was determined by X-ray diffraction. The title compound 1, C₂₉H₂₄FN₃O₂, is monoclinic, space group P2₁/c, a = 9.5653(12), b = 24.394(3), c = 10.7387(15)Å, β = 111.978(2)°, Z = 4, V = 2323.6(5)ų. The central 1,4-dihydropyridine ring adopts a boat confirmation. The intermolecular hydrogen bonds of N-H…O link the molecules forming the dimmers and another amino group connects the two solvent molecules with the dimmer forming the N-H…O hydrogen bonds.
