A novel heterometallic complex [Na2Cu2Gd2(pdc)4(H2O)14·2H2O] (H3pdc = 1H- pyrazole-3,5-dicarboxylic acid) has been synthesized and characterized by IR spectra, elemental analysis, and single-crystal X-ray analysis. The crystal belongs to the monoclinic system, space group P21/c with a = 7.9521(18), b = 12.251(3), c = 22.293(5) , β = 110.173(5)o, V = 2038.5(8) 3, Mr = 1388.13, Z = 2, F(000) = 1352, Dc = 2.261 g/cm3, μ = 4.380 mm-1, the final R = 0.0409 and wR = 0.0622 for 2453 observed reflections with I > 2σ(I). The structural analysis shows that the NaI, CuII and GdII ions are linked together by two kinds of bridging ligands (pdc3- and H2O) to form a main moiety [Na2Cu2Gd2(pdc)4(H2O)14], which can be regarded as a centrosymmetric dimmer of [NaCuGd(pdc)2(H2O)7]. Many hydrogen bonds exist in the complex to build a 3D supramolecular framework.
