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

Two half mol­ecules of the title compound, C(16)H(16)N(2)S(2), 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.
