In compound 1, the eight-coordinated Tb(III) atoms are bridged by carboxylate groups of ntb3– ligands to generate a one-dimensional Tb-carboxylate chain, which is further linked by the ntb3– ligands to form a three-dimensional structure. Compound 1 exhibits characteristic Tb(Ⅲ) luminescent emissions in the solid state.展开更多
