摘要
A series of lanthanide(III)-Ag(I) 4d-4f heterometallic coordination polymers (HCPs) with pen topology, {[Ln(III)-Ag-I(Hbidc)(bidc)(ox)(0.5)(H2O)]center dot H2O}(n) (Ln = Sm 1, Eu 2, Gd 3, Tb 4, Dy 5, Ho 6, Er 7, H(2)bidc = 1H-benzimidazole-5,6-dicarboxylic acid, ox = oxalate), have been synthesized through self-assembly reactions. All seven complexes are isostructural and have three-dimensional 2-fold interpenetrated structures, with both the organic ligand and oxalate groups acting as bridges. These new complexes crystallize with the same unique six-connected three-nodal net described by (10(8).12.16(4).18(2)) (10)(6) topology. The ferromagnetic properties of complex 3 were investigated. Moreover, complexes 1, 2, 4, and 5 exhibit very strong photoluminescence properties and with long lifetimes in the solid state at room temperature.
