Synthesis and structures of two novel heterometallic polymers

The cyanide act as a bridging ligand between metal atoms and it usually gives to polymeric compound with 2D or 3D networks, two novel heterometallic polymers containing CN ligands {[Et4N](2)[WS4Cu4(CN)(2)Br-2]}(n) (1) and [ZnCu4(CN6(dmf)(4)](n) (2) have been synthesized and characterized in this paper.
