title: Poly[[diaqua-deca-μ-cyanido-hexa-cyanidobis-(4-cyano-pyridine)di-μ-pyrimidine-tricopper(II)ditungsten(V)] dihydrate].
abstract: In the polymeric title compound, {[Cu(3)W(2)(CN)(16)(C(4)H(4)N(2))(2)(C(6)H(4)N(2))(2)(H(2)O)(2)]·2H(2)O}(n), the coordination geometry of W is an eight-coordinated bicapped trigonal prism. Five of the CN groups of [W(CN)(8)] are bridged to Cu ions. The coordination geometries of the Cu atoms are each pseudo-octa-hedral; one Cu atom is located on a centre of inversion. The cyano-bridged W-Cu layers are linked by Cu-containing pillars, to form a three-dimensional network with cavities occupied by noncoordinated water and 4-cyano-pyridine mol-ecules.
