title: Poly[tetra-μ-cyanido-dipyridine-cadmium(II)zinc(II)].
abstract: In the title coordination polymer, [CdZn(CN)(4)(C(5)H(5)N)(2)](n), the Zn(II) atom (site symmetry 222) adopts a distorted ZnC(4) tetra-hedral geometry, being coordinated by four crystallographically equivalent cyanide ions. The cyanide ion bridges to a Cd(II) centre via its N atom. The Cd atom (site symmetry 2/m) coordination is a distorted CdN(6) octa-hedron, arising from four cyanide N atoms and two pyridine N atoms. The complete pyridine mol-ecule is generated by m symmetry, with the N atom and one C atom lying on the reflecting plane. In the crystal, the bridging cyanide ions result in a three-dimensional network.
