Bis(μ-N,N′-di-3-pyridylpyridine-2,6-dicarboxamide)bis[dichloridomercury(II)]N,N-dimethylformamide disolvate

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.
