摘要

The crystal structure of 2,3H-2-methyl-4-(4-nitrophenyl)-5-oxobenzopyrano[3,4-e]dihydropyran-2-ol is investigated using X-ray diffraction. The unit cell contains an ethanol molecule that forms hydrogen bonds with O-H and C=O groups of two molecules of the main compound and acts as a proton donor and a proton acceptor in these hydrogen bonds. Owing to these interactions, infinite chains are formed in the crystal. The crystallographic data for the structure of C19H15NO6 . C2H5OH (M = 399.39) are as follows: the crystals are triclinic, space group P1, a 5.5340(3) angstrom, b = 8.0109(4) angstrom, c = 11.0112(5) angstrom, alpha = 88.773(2)degrees, beta = 84.788(2)degrees, gamma = 79.958(2)degrees. and Z =1.
