A Hofmann pyridine complex: poly[tetra-μ-cyano-dipyridinemanganese(II)nickel(II)]

Abstract

The title compound, [MnNi(CN)4(C5H5N)2], has a layered structure of a two-dimensional network complex Mn(py)2Ni(CN)4, in which linkages of cyanide between the equatorial coordination sites of octahedral MnII ions (site symmetry 2/m) and those of square planar NiII ions (site symmetry 2/m) form a square mesh network. Pyridine ligands (located on mirror planes) coordinate to the axial sites of the MnII ions from both sides of the network.
