摘要
Two isostructural metal-organic frameworks formulated as [Gd-7(L)(4)(mu(3)-OH)(8)(HCOO)(DMF)(6)(H2O)]center dot DMF center dot H2O (1) and [Tb-7(L)(4)(mu(3)-OH)(8)(HCOO)(DMF)(5)(H2O)]center dot DMF center dot H2O (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 [Ln(7)(mu(3)-OH)(8)](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.
