摘要：
The open framework compound of [Gd-2(BDA)(3)(DMF)(2)(H2O)(4)]center dot 2DMF (1), prepared by heating GdCl3 with 2,2'-bipyridyl-4,4'-dicarboxylatic acid (BDA) in mixed solvent, is constructed from BDA linking up polymeric [GdO5(DMF)(H2O)(2)](n) tethers. The 1D channels are filled with coordinated and uncoordinated DMF molecules hydrogen bonding to terminal aqua ligands. The study of the temperature dependent magnetic susceptibilities revealed that there are ferromagnetic interactions between intra-chain Gd-III atoms and weak antiferromagnetic interactions between inter-chain Gd-III atoms.
