N,N′-Bis[2-(2-pyridyl)ethyl]dithiooxamide

Abstract

The title compound, C16H18N4S2, has a crystallographic inversion centre at the mid‐point of the central C—C bond. The plane of the dithio­oxamide fragment is approximately perpendicular to the plane of the dimethyl­ene bridge [dihedral angle = 84.8 (1)°], the plane of which is in turn normal to the pyridine ring plane [dihedral angle = 89.80 (8)°]. An inter­molecular N—H⋯N hydrogen bond involving the amide NH group and the pyridine N atom [N⋯N = 3.0503 (18) Å and N—H⋯N = 145.8 (14)°] links the mol­ecules into chains extending along the c axis.
