Abstract

In the title compound, 2-hydroxy-1,2-diphenylethanone 4-ethylthiosemicarbazone, C17H19N3OS, the thiosemicarbazone moiety is planar and has an E configuration. The planar phenyl rings make dihedral angles of 82.34 (8) and 8.07 (17) degrees with the plane of the thiosemicarbazone moiety. The crystal structure contains two intramolecular (N-H...O and N-H...N) and one intermolecular interaction (O-H...S), as well as two C-H...pi(benzene) interactions. Molecules are stacked in columns running along the a axis. Molecules in each column are connected to each other by means of linear O-H...S hydrogen bonds and C-H...pi interactions. In addition, there are also C-H...pi(benzene) interactions between the columns.

摘要

在标题化合物2-羟基-1,2-二苯基乙酮4-乙硫基半卡巴腙(C₁₇H₁₉N₃OS)中,半卡巴腙部分呈平面结构且具有E构型。平面苯环与半卡巴腙部分的平面形成的二面角分别为82.34(8)度和8.07(17)度。晶体结构包含两种分子内相互作用(N-H...O和N-H...N)和一种分子间相互作用(O-H...S),以及两种C-H...π(苯)相互作用。分子沿a轴方向堆积成列。每列中的分子通过线性O-H...S氢键和C-H...π相互作用相互连接。此外,列与列之间也存在C-H...π(苯)相互作用。
