Crystal structure of N,N′-bis(4-methylphenyl)dithiooxamide

Abstract

Two half molecules of the title compound, C16H16N2S2, are present in the asymmetric unit and both molecules are completed by crystallographic inversion centers at the mid-points of the central C—C bonds: the lengths of these bonds [1.538 (5) and 1.533 (5) Å] indicate negligible electronic delocalization. The trans-dithiooxamide fragment in each molecule is characterized by a pair of intramolecular N—H...S hydrogen bonds. In the crystal, molecules are linked by weak C—H..π interactions, generating a three-dimensional network.
