Poly[[di-aqua-deca-μ2-cyanido-κ(20) C:N-hexa-cyanido-κ(6) C-bis-(μ2-5-methyl-pyrimidine-κ(2) N:N')bis-(5-methyl-pyrimidine-κN)tricopper(II)ditungstate(V)] dihydrate].
In the title complex, {[Cu3[W(CN)8]2(C5H6N2)4(H2O)2]·2H2O} n , the coordination polyhedron of the eight-coordinated W(V) atom is a bicapped trigonal prism, in which five CN groups are bridged to Cu(II) ions, and the other three CN groups are terminally bound. Two of the Cu(II) ions lie on a centre of inversion and each of the three independent Cu(II) cations is pseudo-octahedrally coordinated. In the crystal structure, cyanido-bridged-Cu-W-Cu layers are linked by pillars involving the third independent Cu(II) ion, generating a three-dimensional network with non-coordinating water mol-ecules and 5-methyl-pyrimidine mol-ecules. O-H⋯O and O-H⋯N hydrogen bonds involve the coordinating and non-coordin-ating water mol-ecules, the CN groups and the 5-methyl-pyrimidine mol-ecules.
