Two pillared-layer coordination polymers based on different cadmium/carboxylate units and 2-amine-4,4′-bis(1-imidazolyl)-bibenzene

Two 3D coordination polymers [Cd(5-HO-1,3-BDC)(abimb)]n and {[Cd3(OAIP)2(abimb)2(H2O)3]·H2O}n were generated from solvothermal reactions of CdCl2 with 2-amine-4,4′-bis(1-imidazolyl)-bibenzene (abimb) and 5-hydroxy-1,3-benzenedicarboxylic acid (5-HO-1,3-H2BDC) or 5-oxyacetate isophthalic acid (H3OAIP). Both complexes were structurally characterized by elemental analysis, IR, and X-ray crystallography and their thermal and luminescent properties were studied.
