Abstract: In the title complex, {[Cu₂Mo(CN)₈(C₁₂H₃₀N₆O₂)₂]·4H₂O}_n, the polyhedron around Mo has site symmetry $\\overline1$ 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.
