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 = 1340.5
(4), c = 1343.3(4) pm. The structure is polymeric and consists of alte
rnate arrays of tetrahedrally and octahedrally coordinated zinc atoms,
bridged by CN ligands. Two pyridine molecules ligate at the axial pos
itions of the octahedrally coordinated zinc atoms.
