Bis(μ-N,N'-di-3-pyridylpyridine-2,6-dicarboxamide)bis-[dichloridomercury(II)] N,N-dimethyl-formamide disolvate.

ABSTRACT: The asymmetric unit of the binuclear title complex, [Hg(2)Cl(4)(C(17)H(13)N(5)O(2))(2)]·2C(3)H(7)NO, contains one-half of the centrosymmetric mol-ecule and one dimethyl-formamide solvent mol-ecule. The Hg(II) atom is four-coordinated by two N atoms from two ligands and two Cl atoms in a distorted tetra-hedral coordination geometry. Intra-molecular 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.
