A new 3D coordination polymer {[Gd2(bpdc)3(H2O)3]·H2O}n(1) has been isolated from the reaction of 2,2′-bipyridine-4,4′-dicarboxylic acid (H2bpdc) and Gd(III) salts under hydrothermal conditions. Single-crystal X-ray diffraction study shows that compound 1 is constructed from Gd2-based second building units (SBUs) [Gd2(bpdc)3(H2O)3] and displays a 3D (3,4,8)-connected net with (42·6)(32·42·52)(32·45·54·611·76) topology. A thermogravimetric analysis of 1 shows a high thermal stability. The magnetic behavior of 1 reveals a weak antiferromagnetic interaction between Gd(III) ions.
