SYNTHESIS, X-RAY CRYSTAL STRUCTURE AND IR STUDY OF NEW TRINUCLEAR, BASE CARBOXSYLATE COMPLEX OF [Cu3O(OAc)6(H2O)3]Cl.CH3OH.6H2O

Abstract

The synthesis of [Cu3O(OAc)6(H2O)3]Cl.CH3OH.6H2O is described. The X-ray crystallographic study of the<br />complex revealed an isosceles triangle of copper atoms with a triply bridging oxo atom nearly in the plane of the<br />triangle. The coordination sphere around each metal center is close to distorted octahedral and the central<br />{Cu3(μ3-O)} core is planar. Every two copper atoms were connected to each other, by two bridge of alkyl<br />acetate.The water molecule as a monodentate ligand is connected to every copper. Counter ion of this complex<br />is a group that contain one atom of chlorine, one molecule of methanol and six molecule of water. This<br />compound crystallizes in the orthorhombic system, space group P21212, with four molecules per unit cell. The<br />unit cell dimension were a = 1359.3(1)Å, b = 2317.3(1)Å, c = 908.4(1) Å, α = 90°, β = 90°, γ = 90° and V =<br />2861.4(4)106(pm3). The final R value is 0.0667 for 5321 measured reflections. The identification, IR<br />investigation and elemental analysis data are consistent with a unit cell composed of<br />[Cu3O(AcO)6(H2O)3]Cl.CH3OH.6H2O
