Abstract
The asymmetric unit of the binuclear title complex, [Hg2Cl4(C17H13N5O2)2]·2C3H7NO, contains one-half of the centrosymmetric molecule and one dimethylformamide solvent molecule. The HgII atom is four-coordinated by two N atoms from two ligands and two Cl atoms in a distorted tetrahedral coordination geometry. Intramolecular N—H⋯O hydrogen bonds may be effective in the stabilization of the structure. In the crystal structure, π–π contacts between pyridine rings [centroid-to-centroid distances 3.629 (3) and 3.595 (3) Å] may further stabilize the structure.
