Abstract

The title compound, C22H21NO3 belongs to the monoclinic system, space group P21/c  with  a = 9.3400 (3) Å, b = 22.1653 (8) Å, c = 8.7044 (3) Å, α = γ = 90˚ , β = 105.549 (1)˚,             V = 1736.07 (10) Å3, Z = 4, Dc = 1.3291(1) Mg /m3, F(000) = 736, R = 0.0358 and wR = 0.0959, S= 1.082, T = 296 K. In the title compound, C22H21NO3, the nitrogen- containing  ring  of  the  pyranoquinoline moiety adopts a slightly distorted half-chair conformation and the oxygen- containing ring adopts a slightly distorted chair conformation. The benzene rings make a dihedral angle of 48.07(9) ˚. In the crystal, weak C—H…O and π—π interactions link the molecules into chains extending along the a-axis direction. The crystal structure of the title compound was characterized by X-ray diffraction studies and spectroscopic 1H NMR technique.

 

Keywords: Pyranoquinoline, benzene ring, coumarin, methyl substituted derivative
