Abstract:
The title compound, [Cu(NH3)4-(μ2-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 CuN5 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 tetra-gonal-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 mol-ecules inter-act by N-H⋯N hydrogen bonds, resulting in the formation of a three-dimensional network.
