Abstract

ABSTRACT: The X-ray crystal structure of 3-(2-(4-morpholinophenyl)-2-oxoethyl)-5, 5-diphenylimidazolidine-2, 4-dione (2 ) [C27 H25 N3 O4 : MF = 455.50, monoclinic, P 21 /c, a = 6.2038 (2) Å, b = 20.8905 (6) Å, c = 18.3361 (6) Å, b = 97.594 (2) ο, V = 2355.53 Å 3, Z = 4, D calc = 1.284 Mg m −3, λ = 1.54178 Å] was determined. The crystal packing confirmed the occurrence of two conformers of opposite conformation. Conformational aspects of compound2 have pointed out two factors that determine the conformation of the system under investigation: first, the intermolecular hydrogen bonding of the crystal packing, which stabilizes and favors the occurrence of two independent molecules, and the second factor is the steric hindrance among substituents.
