Abstract

The asymmetric unit of the title compound, C(22)H(15)Cl(4)NO(2)·0.5H(2)O, consists of a (3E,5E)-1-acryloyl-3,5-bis-(2,4-dichloro-benzyl-idene)piperidin-4-one mol-ecule and a half-mol-ecule of water (the O atom of the water mol-ecule lies on a twofold axis). The piperidin-4-one ring adopts an envelope conformation. The dihedral angle between the two terminal benzene rings is 8.84 (11)°. In the crystal, mol-ecules are connected by C-H⋯O hydrogen bonds forming supra-molecular chains along the c axis. Furthermore, adjacent chains are inter-connected by the water mol-ecules via O-H⋯O hydrogen bonds.

摘要

标题化合物C(22)H(15)Cl(4)NO(2)·0.5H(2)O的不对称单元由一个(3E,5E)-1-丙烯酰基-3,5-双-(2,4-二氯亚苄基)哌啶-4-酮分子和半个水分子组成(水分子的O原子位于二重轴上)。哌啶-4-酮环呈信封构象。两个末端苯环之间的二面角为8.84 (11)°。在晶体中,分子通过C-H⋯O氢键连接,沿c轴形成超分子链。此外,相邻的链通过水分子经由O-H⋯O氢键相互连接。
