A new copper complex, Cu2 (pba)(bpy)2Cl2·4H2O (here pba was pro-pylenebis (oxamic acid), bpy was bipyridine), was synthesized. Crystal structure of thetitle complex was determined. It belongs to the tetragonal system, molecular formulaCu2Cl2Oi0N6C27H32, Mr = 798. 58, space group P4t212, a = b = 9. 484(4), c =35.918(9) A, V = 3235(2) A3, Dx = 1. 64gcm-3 and F(000) = 1568, μ =1. 546mm 1 for Z = 4. The crystal structure was solved by direct methods for final R =0.048 and Rω, = 0.060 for 1992 observed reflections with I ＞3a (I). The complex hasa C2 symmetry. A chloride anion, two nitrogen atoms from bipyridine and two oxygenatoms from the oxamide carbonyl and carboxyl coordinated to the CuⅡ ion forming asquare pyramidal geometry. In each molecule, two bpy are almost parallel.
