title: (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.
abstract: The title compound, C(14)H(11)NS, 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.
