Tetra­ammine-2κ(4) C-μ-cyanido-1:2κ(2) C:N-tricyanido-1κ(3) C-copper(II)palladium(II)

The title compound, [Cu(NH(3))(4)-(μ(2)-NC)—Pd(CN)(3)], is a binuclear copper(II)palladium(II) complex, in which the Cu(II) coordination is defined by four ammine ligands and one bridging cyanide ligand. The Cu—N bond lengths in the base of the resulting CuN(5) pyramid are in the range 2.016 (3)–2.024 (3) Å and the apical Cu—N( C) distance is 2.385 (4) Å. Based on the τ parameter, the shape of the coordination polyhedron is tetra­gonal–pyramidal (τ = 0). All atoms of the square-planar tetracyanidopalladate(II) moiety and the Cu(II) ion are located on a mirror plane. The electroneutral mol­ecules inter­act by N—H⋯N hydrogen bonds, resulting in the formation of a three-dimensional network.
