Amixed ligands chromium(III) complex with bidentate ligands: 2,2_-bipyridyl (bpy) and malonic acid deprotonated (mal-, malonate ion), has been synthesized, investigated and characterized structurally and spectroscopically. Electronic spectra of this complex were recorded in an aqueous solution at room temperature. The 'poor' experimental contours were resolved into the component bands by Gaussian analysis. The spectra were interpreted using C2v symmetry. The resolved spectra have been treated using an angular overlap model (AOM). The effect of _- and _-bonding of the bidentate ligands upon the chromium(III) ion in aqueous solution was described and discussed.
