title: catena-Poly[[[tetra-kis-(cyanido-κC)tungstate(IV)]-di-μ-cyanido-κC:N-bis-[diaqua-(2,2'-bipyridyl-κN,N')manganese(II)]-di-μ-cyanido-κN:C] hexa-hydrate].
abstract: The polymeric title compound, {[Mn(II) (2)W(IV)(CN)(8)(C(10)H(8)N(2))(2)(H(2)O)(4)]·6H(2)O}(n), has a one-dimensional cyanide-bridged Mn(II)-W(IV) bimetallic assembly. The coordination geometry of the W(IV) atom is eight-coordinate square-anti-prismatic and that of each of the Mn(II) atoms is six-coordinate distorted octa-hedral. Two pairs of CN ligands of W(CN)(8) are bridged to two Mn(II) atoms, the remaining CN ligands being terminal. Each Mn(II) atom is additionally coordinated by a bidentate 2,2'-bipyridyl ligand and two water mol-ecules. The crystal structure is stabilized by O-H⋯O and O-H⋯N hydrogen bonds.
