| Abstract: Six new lanthanide metal coordination polymers, Ln2(SSA)2(phen)4(H2O)2(Ln=Er(Ⅲ) (1) and Yb(Ⅲ) (2)), [La2(SSA)2(phen)2(H2O)4·(phen)·(H2O)1.33]n(3) and [Ln(SSA)(bpdo)0.5(H2O)·(H2O)]n(Ln=Nd(Ⅲ) (4), Sm(Ⅲ) (5), Eu(Ⅲ) (6), SSA=5-sulfosalicylic acid, phen=phenanthroline and bpdo=4,4′-bipyridine-N,N′-dioxide), were synthesized under hydrothermal conditions and structurally characterized. Compounds 1 and 2 are isostructural with the butterfly-like binuclear cores, which are further connected by hydrogen bonds and π-π interactions to generate a 3D coordination network. Compound 3 exhibits a 1D infinite ladder-like chain along a-axis, where the hydrogen bonds and π-π stacking interaction play important roles in the formation of the coordination network. Compounds 4～6 possess 3D frameworks with interweaving single-helical chains. In addition, the thermal stabilities and fluorescent properties of the six compounds are studied as well. Compound 3 displays intense blue emission in solid state when excited. CCDC: 612600, 1; 612602, 2; 612601, 3; 653354, 4; 653355, 5; 653356, 6. |
