Synthesis, structure analysis and catalytic activity of two Ln-coordination polymers containing benzophenone-4,4'-dicarboxylate linker

Two lanthanide-coordination polymers (Ln-CPs) containing benzophenone-4,4'-dicarboxylate (bpndc(2-)) linker, namely [Er-2(bpndc)(3)(DMF)(2)] (1) and [Yb-2(bpndc)(3)(DMF)(2)] (2) were synthesized and characterized using X-ray crystallography and spectroscopic methods. The topological analysis revealed that both compounds are chiral three-dimensional uninodal 5-connected net of type yfh. These Ln-CPs showed good stability and thus were used as heterogeneous catalysts for the acetalization of glycerol. This study provides some further evidence supporting the effectiveness of Ln-CPs as potential Lewis acid catalysts for chemical transformations.
