Two 2-D homometallic and heterometallic Schiff-base complexes bridged by dicyanamide

Two Schiff-base complexes composed of homometallic and heterometallic dinuclear units, [Zn2(salpn)]2+ and [CuCd(salpn)]2+, have been prepared and characterized. The dinuclear second building units are connected by dicyanamide (dca) ligands, forming 2-D layer structure. Zinc(II) complex displayed structure-related photoluminescence properties in the solid state.
