Synthesis, structure and properties of a copper complex Cu2(μ-PhCOO)2(μ-CH3COO)2(CH3OH)2

The title Complex Cu-2(mu-PhCOO)(2)(mu-CH3COO)(2)(CH3OH)(2) 1 (C20H24Cu2O10, M-r = 551.47) has been synthesized by the reaction of Cu(OAc)(2)center dot H2O with benzoic acid, and its crystal structure was determined by X-ray diffraction method. Complex 1 belongs to orthorhombic, space group Pbca with a = 13.083(6), b = 8.078(4), c = 21.566(2) angstrom, V = 2279(2) angstrom(3), Z = 4, D-c = 1.607 g/cm(3), F(000) = 1128, mu(MoK alpha) = 1.918 mm(-1), the final R = 0.0506 and wR = 0.1382. Each Cu(II) ion is coordinated by five oxygen atoms from two benzoic acids, two acetic acids and one methanol molecule in a slightly distorted square pyramidal environment. The title molecules construct a 2-D layer via the hydrogen bonds O-H center dot center dot center dot O. Solid-state photoluminescent investigation reveals that complex 1 displays strong emissions. IR and TG-DTA studies are also presented.
