Kristallstruktur des cyanoverbrückten polymeren Zinkcyanid-Pyridin-Komplexes [Zn(py)2][Zn(CN)4]

Pickardt, Joachim; Staub, Benedikt

The reaction of aqueous solutions of potassium tetracyanozincate, zinc chloride, and pyridine yields crystals of [Zn(py)2][Zn(CN)4], The crystals are orthorhombic, space group Cccm, a = 926.7(4), b = 1340.8(4), c = 1343.3(4) pm. The structure is polymeric and consists of alternate arrays of tetrahedrally and octahedrally coordinated zinc atoms, bridged by CN ligands. Two pyridine molecules ligate at the axial positions of the octahedrally coordinated zinc atoms.
