Structure elucidation and topological studies of new lanthanide-organic frameworks (UPMOFs) synthesised via solvothermal route using mixed dicarboxylate linkers of 1,4-benzenedicarboxylic acid and 4,4-oxybis benzoic acid

The new lanthanide-organic frameworks (UPMOFs) were solvothermally synthesised using M(NO3)3·6H2O (M = La, Ce, Pr and Nd) metal salts with mixed dicarboxylate ligands namely, 1,4-benzenedicarboxylic acid (H2BDC) and 4,4-oxybis benzoic acid (H2OBA). The successful synthesis produced a series of four...
