Structural diversity of four coordination polymers based on asymmetric dicarboxylate: Effect of metal ions and N-donor ligands

Four novel d10 metal coordination polymers were synthesized and characterized. 1 shows a 1D square-wave-like chains. 2 is 1D ring chain structure based on dinuclear cadmium unit. 3 forms a 1D right-handed helical chain. 4 possesses a 2D network structure based on octanuclear silver clusters cross-linked by bdam2− and dpe ligands. Especially the (bdam)2− ligands in 1-4 adopt four different coordination modes. In addition, the thermal stability and luminescence properties of 1-4 were also studied.
