Abstract

The crystal structure determination of the title compound, C(15)H(14)N(2)O, confirms the cis relationship between the phenyl groups at the 4- and 5-positions on the imidazolidine ring. The dihedral angle between the two phenyl rings is 48.14 (6)°. In the crystal structure, inter-molecular N-H⋯O hydrogen bonds link mol-ecules into centrosymmetric dimers. These dimers are, in turn, linked into a two-dimensional network via weak N-H⋯π(arene) inter-actions and π-π stacking inter-actions with centroid-centroid distances of 3.6937 (11) Å.

摘要

标题化合物C(15)H(14)N(2)O的晶体结构测定证实了咪唑烷环上4位和5位苯基之间的顺式关系。两个苯环之间的二面角为48.14 (6)°。在晶体结构中，分子间的N-H⋯O氢键将分子连接成中心对称的二聚体。这些二聚体又通过弱的N-H⋯π(芳烃)相互作用和质心-质心距离为3.6937 (11) Å的π-π堆积相互作用连接成二维网络。
