Crystal structure of N,N′-bis(4-methyl-phenyl)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 midpoints 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⋯πs interactions, generating a three-dimensional network.
