The X-ray crystal structure of 3-(2-(4-morpholinophenyl)-2-oxoethyl)-5,5-diphenylimidazolidine-2,4-dione (2) [C27H25N3O4: MF = 455.50, monoclinic, P21/c, a = 6.2038 (2) Å, b = 20.8905 (6) Å, c = 18.3361 (6) Å, b = 97.594 (2)ο, V = 2355.53 Å3, Z = 4, Dcalc = 1.284 Mg m−3, λ = 1.54178 Å] was determined. The crystal packing confirmed the occurrence of two conformers of opposite conformation. Conformational
摘要 3-(2-(4-morpholinophenyl)-2-oxoethyl)-5,5-diphenylimidazolidine-2,4-dione (2) [C27H25N3O4: MF = 455.50, 单斜晶系, P21/c 的 X 射线晶体结构, a = 6.2038 (2) Å, b = 20.8905 (6) Å, c = 18.3361 (6) Å, b = 97.594 (2)ο, V = 2355.53 Å3, Z = 4, Dcalc = 1.284 Mg m−3, λ = 1.54178 Å] 已确定。晶体堆积证实了两种相反构象的构象异构体的出现。化合物2的构象方面指出了决定所研究系统构象的两个因素:第一,晶体堆积的分子间氢键,稳定并有利于两个独立分子的出现,第二个因素是空间位阻取代基之间。
