Synthesis and crystal structure of binuclear complex of copper(II) chloroacetate with acetamine

The title complex, Cu-2(O2CCH2Cl)(4)[CO(NH2)CH3](2), crystallizes in space group P2(1)/a with a = 7. 616(4) , b = 18. 665 (5) , c = 7. 949(5) Angstrom , beta = 106. 29 (5)degrees. V = 1084(1) Angstrom(3), Z = 2, M-r = 619. 19, D-c = 1. 896 g/cm(3); mu = 25. 05 cm(-1) and F(000) = 620. 00, R = 0. 045 and R-w = 0. 054 for 1807 observable reflections. X-ray crystal structure analysis revealed that two Cu atoms are bridged by four chloroacetate groups, and the acetamine ligands are bonded by O(carboxide) to the terminal Cu atoms of each dimeric unit. The coordination geometry of Cu atom is a distorted octahedral configuration. The distance between the two Cu atoms is 2. 648(1) Angstrom.
