摘要：
A new coordination polymer [Gd(Sfdb)(NO3)(DMF)2] · 2H2O (Sfdb = 4,4′-sulfonyldibenzoic acid) has been synthesized under hydrothermal conditions and characterized by elemental analysis, IR, TG and single-crystal X-ray diffraction (CIF file CCDC no. 1023460). The X-ray diffraction analysis shows that I (C20H24N3O12SGd) crystallizes in the monoclinic crystal system, which reveals that I is a 3D supramolecular framework assembled by the intermolecular hydrogen bonds. Moreover, the magnetic studies of I showed that there exist antiferromagnetic interactions between the Gd(III) centres. The unit cell parameters for I: a = 33.453(3), b = 10.5469(10), c = 18.7895(18) Å, β = 123.7670(10)°, V = 5511.0(9) Å3, Z = 8.
