摘要：

Mixed-carboxylato beta-diketonato complexes of chromium (III) (R=C13H27, C15H31 or C17H35 and L=CH3OH) [Cr3O(OOCR)(3)(dike)(3)L-3](+) have been synthesized by enforced substitution reactions of [Cr3O(OOCCH3)(7)(H2O)] first with straight chain fatty acids (myristic, palmitic or stearic acid) and then with P-diketones (HP-dike) like acetylacetone(Hacac) or benzoylacetone(Hbzac) in toluene under reflux. These are new type of oxo-bridged chromium(III) complexes in which one ligand is a fatty acid while the other one is a beta-diketone. The complexes were characterized by elemental analyses, spectral (infrared, electronic, FAB mass and powder XRD) studies, molar conductance and magnetic susceptibility measurements. Bridging coordination modes for both carboxylate and beta-diketonate anions were indicated by presence of nu(asym)(Cr3O) vibrations in the infrared spectra. Trinuclear nature of the complexes and their structural features have been discussed on the basis of physicochemical studies. (c) 2005 Elsevier B.V. All rights reserved.
