A new o-phthalato-bridged oxamide copper(Ⅱ) complex 1, {[Cu2(oxap)](pht). 4H2O}n (oxap=N, N'-bis(2-aminopropyl)oxamide, pht= phthalate dianion), has been prepared and structurally characterized. It crystallizes in monoclinic, space group C2/c with a=23.424(4), h=7.9696(14), c=15.727(3)A°,β=129.617(2)°, C16H28Cu2N4O10, Mr=563.50, V=2261.6(7) A°, Z=4, Dc=1.655 g/cm^3, μ(MoKα)=1.939 mm^-1, F(000) = 1160, the final R=0.0393 and wR=0.0928 for 1707 observed reflections with I〉2σ(1). Single-crystal X-ray analysis reveals that 1 displays a one-dimensional zigzag chain structure, in which each Cu(oxap) moiety adopting trans-conformation is connected by ,μ1,6-phthalate anion bridges, and these zigzag chains are further linked by another ,μ1,6-phthalate anion bridge to form a 2D sheet structure. The polar guest water molecules reside in the inter-and intrasheets to stabilize the whole crystal structure. 展开更多
