| 摘 要： | 1 INTRODUCTION Coordination polymers are a family of materials composed of 1D chains, 2D sheets, and 3D networks of metal-organic building blocks connected via co- valent and hydrogen bonds. Recently, they have re- ceived increasing attention for their fascinating struc- tures and topological features1～4]. The complex as ligands approach is one of the best strategies to de- sign and synthesize polynuclear species, and a good example of ‘complex ligand’ is represented by mono- nuclear…

One and Two-dimensional Structures of a New Oxamido Copper(II) Complex with Phthalato Bridged |

| Abstract: | 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), b = 7.9696(14), c = 15.727(3) , β = 129.617(2)o, C16H28Cu2N4O10, Mr = 563.50, V = 2261.6(7) 3, Z = 4, Dc = 1.655 g/cm3, μ(MoKα) = 1.939 mm-1, F(000) = 1160, the final R = 0.0393 and wR = 0.0928 for 1707 observed reflections with I > 2((I). Single-crystal X-ray analysis reveals that 1 displays a one-dimensional zigzag chain structure, in which each Cu(oxap) moiety adopting trans-confor- mation 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. |
