Poly[bis[3,10-bis(2-hydroxyethyl)-1,3,5,8,10,12-hexa­azacyclo­tetra­deca­ne]tetra-μ-cyanido-tetracyanidodicopper(II)molybdenum(IV)] tetra­hydrate]

In the title complex, {[Cu(2)Mo(CN)(8)(C(12)H(30)N(6)O(2))(2)]·4H(2)O}(n), the polyhedron around Mo has site symmetry [Image: see text] with a distorted square-antiprismatic shape, while the Cu atom (2 symmetry) is in a distorted axially elongated octa­hedral coordination environment. The uncoordinated water molecule is disordered over three sites with occupancies of 0.445 (7), 0.340 (7) and 0.215 (7). Mo and Cu atoms acting as basic components are connected by an Mo—CN—Cu—NC—Mo— linkage to form a distorted diamond-like network. Additional hydrogen bonding between the N—H groups and the water molecules stabilizes this arrangement.
