Abstract

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