Crystal structure and Hirshfeld surface analysis of 3-(2,6-di-chloro-phen-yl)-1,5-bis-(thio-phen-2-yl)pentane-1,5-dione.

Abstract

In the crystal of the title compound, C19H14Cl2O2S2, mol-ecules are linked by inter-molecular C-H⋯O hydrogen bonds, forming a square-ring around a fourfold rotation axis parallel to the c-axis. In addition, C-H⋯π and π-π inter-actions [centroid-to-centroid distances = 3.759 (3) and 3.760 (3) Å] connect mol-ecules, forming a three-dimensional network. Two thio-phene rings are disordered with a 180° rotation over two positions; the first in a 0.686 (2)(3):0.314 (2) ratio and the second in a 0.787 (2):0.213 (2) ratio. The major contributions to the Hirshfeld surface are from H⋯H (32.4%), C⋯H/H⋯C (25.6%), Cl⋯H/H⋯Cl (17.2%) and O⋯H/H⋯O (14.4%) contacts.
