Synthesis, crystal structures and properties of lanthanide-organic frameworks based benzene carboxylates with two/three-dimensional structure

► Five lanthanide coordination polymers based on 1,3-H2BDC were obtained. ► The polymers were structurally characterized by single-crystal X-ray diffraction. ► Coordination polymers 1-5 display different topological structures. ► They show characteristic emissions of lanthanide ions in the solid state.
