Poly[aqua­hexa­benzimidazole­octa-μ-cyanido-octa­cyanidotricopper(II)ditungstate(V)]

In the polymeric title compound, [Cu(3)W(2)(CN)(16)(C(7)H(6)N(2))(6)(H(2)O)](n), the coordination geometry of the W(V) atom is eight-coordinate dodeca­hedral, where four CN groups of [W(CN)(8)] are bridged to Cu(II) ions, and the other four CN groups are not bridged. The coordination geometries of t...

Descripción
Sumario:In the polymeric title compound, [Cu(3)W(2)(CN)(16)(C(7)H(6)N(2))(6)(H(2)O)](n), the coordination geometry of the W(V) atom is eight-coordinate dodeca­hedral, where four CN groups of [W(CN)(8)] are bridged to Cu(II) ions, and the other four CN groups are not bridged. The coordination geometries of the Cu(II) ions are five-coordinate pseudo-square-based pyramidal. There are two distinct Cu sites, which build and link the cyanido-bridged Cu—W ladder chains. Successive connections lead to the formation of a two-dimensional network. The H atoms of a coordinated water molecule and the imino groups form hydrogen bonds to the N atoms of non-bridged CN groups.
