Synthesis, structure, luminescence and magnetic property of camphorate coordination polymers containing 5,6-dimethylbenzimidazole auxiliary ligand

Three camphorate coordination polymers were prepared with 5,6-dmbi auxiliary ligand. 1 displays a 1D helical chain structure. 2 exhibits a 2D chiral network with 3-connected {4.82} topology. 3 is a 2D achiral polymer assembled from d-cam and l-cam ligands. They are all thermally stable up to 316-425 °C. 1 and 2 show violet luminescence. 3 displays an antiferromagnetic interaction.
