Crystal structure of N,N'-bis-(4-methyl-phen-yl)di-thio-oxamide.

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) A] 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.
