摘要: Nine novel heterometallic coordination polymers [Ln2Ni(Hbidc)2(SO4)2(H2O)8]n (Ln = Pr (1), Sm (2), Eu (3), Gd (4), Tb (5), Dy (6), Ho (7), Er (8), Yb (9), H3bidc 1H-benzimidazole-5,6-dicarboxylic acid) have been synthesized under hydrothermal conditions and characterized by elemental analysis, FT-IR, TG analysis single crystal X-ray diffraction. revealed that all complexes present almost identical three-dimensional (3D) structures with PtS-type topology. Complexes 1–7 are isomorphous, the structure variation of 8 9 is induced lanthanide contraction effect. In additional, luminescence properties 2, 3 5–7, magnetic 4 6–8 were investigated.
