The two linear hetero-trinuclear metallic complexes with Cu2+, Ni2+ and Zn2+ ions, [CuNi2 {(CHO2)(SALPD)[(CH3)2NCHO]}2],(I) and [ZnNi2{(CHO2)(SALPD)[(CH3)2NCHO]}2],(II), form crystals which belong to the monoclinic system, space group P21/c, with unit cell dimensions a=10.537(4), b=16.612(5), c=13.837(3) Å, β=111.09(5)°, V=2259.8(12) Å3 in (I) and a=10.525(4), b=16.658(5), c=13.826(3) Å, β=111.11(5)°, V=2261.4(8) Å3 in (II), respectively. The coordinations around the M (Ni2+, Cu2+, Zn2+) ions in the title complexes are distorted octahedrals. The stereochemistries of the bridge ligands, linking to the metal ions each other, are changed between Ni...M (Cu2+, Zn2+) distances. The Ni...M (Cu2+, Zn2+) distances are 3.0469(13) and 3.0645(14), respectively.
