Description
Summary:Two isostructural metal-organic frameworks formulated as [Gd7（L）4（μ3-OH）8（HCOO）（DMF）6（H20）].DMF·H2O （1） and [Tbv（L）4（P3-OH）8（HCOO）（DMF）5（HzO）]·DMFoH2O （2） （H3L=3,5-di（4＇-carboxylphenyl）benzoic acid） have been synthesized and structurally characterized. The building blocks of the structures are the heptanuclear lanthanide clusters of the dicubane-like type [Lnv7（μ3-OH）s]13＋ （Ln=Gd, Tb） which are formally assembled into porous three-dimensional networks through the linkage of L. Variable temperature magnetic studies down to 2 K reveal antiferromagnetic interactions in complex 1. Furthermore, the fluorescence property of 2 was also studied.
