Exploring methyl-3-hydroxy-5-carboxy-2-thiophenecarboxylate and varying flexible bis(imidazole)-based synthons as building blocks for the construction of diverse cadmium coordination polymers

Three new Cd(II)-based coordination polymers with unique structures and topologies have been successfully constructed using a new designed methyl-3-hydroxy-5-carboxy-2-thiophenecarboxylate ligand in the presence of bis(imidazole) ligands.219
