(E)-3-(4-Methyl­phen­yl)-2-(2-thien­yl)­acrylonitrile has Z′ = 0.75 in the space group C2/m: fourfold disordered mol­ecules lie in channels enclosed by fully ordered mol­ecules

摘要

The title compound, C14H11NS, crystallizes with Z′ = 0.75 in the space group C2/m. Two independent mol­ecules are present, one of which lies with all the non-H atoms on a mirror plane, while the other is fourfold disordered across a site of 2/m symmetry. The ordered mol­ecules are stacked such that they enclose continuous channels running along twofold rotation axes, and the disordered mol­ecules are positioned within these channels.
