摘要：
The X-ray crystal structure of 3-(2-(4-morpholinophenyl)-2-oxoethyl)-5,5-diphenylimidazolidine-2,4-dione (2) [C27H25N3O4: MF = 455.50, monoclinic, P2(1)/c, a = 6.2038 (2) angstrom, b = 20.8905 (6) angstrom, c = 18.3361 (6) angstrom, b = 97.594 (2), V = 2355.53 angstrom(3), Z = 4, D-calc = 1.284 Mg m(-3), = 1.54178 angstrom] was determined. The crystal packing confirmed the occurrence of two conformers of opposite conformation. Conformational aspects of compound 2 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.
