| 摘 要： | A new compound,[Cu(mal)(tmdpy)(H2O)]·4H2O(1,H2mal = malonic acid,tmdpy = 4,4'-trimethylenedipyridine) has been synthesized by the hydrothermal synthesis and structurally characterized by X-ray crystallography. It crystallizes in triclinic,space group P1 with a = 9.1662(6),b = 10.6266(7),c = 11.3056(7) ,α = 84.6390(10),β = 72.1030(10),γ = 73.0420(10) o,V = 1002.37(11) 3,C16H26CuN2O9,Mr = 453.93,Z = 2,Dc = 1.504 g/cm3,μ = 1.140 mm-1,F(000) = 474,R = 0.0375 and wR = 0.0975 for 3187 observed reflections(I > 2σ(I)) . In the structure of 1,the tmdpy ligands link the [Cu(mal)(H2O) ] units into an infinite chain,and the water molecules and carboxylate oxygen donors(O(2) and O(4)) from the mal ligands cooperatively built an interesting hydrogen bonding network with unprecedented pseudo water tape substructures.
