Abstract

The title compound, 4-Methyl-3-phenyl-6-(4-phenyl-5H-indeno[1,2- b]pyridin-2-yl)coumarin chloroform monosolvate, C34H23NO2.CHCl3, was synthesized and characterized by spectroscopic techniques such as 1H-NMR, 13C-NMR, IR and mass spectroscopy. In addition to that the title compound was also characterized by single crystal x-ray diffraction method. The compound crystallizes in the monoclinic space group P21/n with unit-cell parameters: a = 9.2340(2), b = 14.1626(3), c = 22.2540(5)Å,  = 90,  = 100.121(2),  = 90˚, Z = 4. The crystal structure was solved by direct methods using single-crystal X-ray diffraction data, and refined by full-matrix least-squares procedures to a final R-value of 0.0695 for 4979 observed reflections.
