摘　　要：The ligand [1, 2-bis(4-pyridinecarboxamido) ethane] (L) and the coordination polymer {[Cu(L)(2)(H2O)].(NO3)(2).6H(2)O}(n)(1) have been synthesized and characterized by IR and H-1 NMR, spectra. Their molecular structures and the packing of 1 have been determined by single-crystal X-ray diffraction analysis. The Cu(II) in 1 is bridged by two ligand forming an infinite one-dimensional chain like structure and L in I adopts a different conformation from its free state. 1 belongs to monoclinic, space group P2(1)/n, a = 1.2896(3) nm, b = 1.2552(8) nm, c = 2.2903(19) nm, beta = 93.04(5)degrees, Z = 4, V = 3.702(4) nm(3). The TG and DTG experiments showed that the uncoordinated H2O can be removed at low temperature by heating, and it does not decompose until 250 degreesC.The ligand [1, 2-bis(4-pyridinecarboxamido) ethane] (L) and the coordination polymer {[Cu(L)(2)(H2O)].(NO3)(2).6H(2)O}(n)(1) have been synthesized and characterized by IR and H-1 NMR, spectra.
