title: Crystal structure of N,N'-bis-(4-methyl-phen-yl)di-thio-oxamide.
abstract: Two half mol-ecules of the title compound, C16H16N2S2, are present in the asymmetric unit and both mol-ecules 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-di-thio-oxamide fragment in each mol-ecule is characterized by a pair of intra-molecular N-H⋯S hydrogen bonds. In the crystal, mol-ecules are linked by weak C-H..π inter-actions, generating a three-dimensional network.
