%X The visible spectra of [UO2L5]2+, where L = OCMe(NMe2), OCMe(NHMe), OCH(NMe2), OCH(NHMe), OP(OMe)3 and OPMe(OMe)2 ; and [UO2 {OP(NMe2)3}]2+, in CH2Cl2 solution are reported. The spectra have been resolved into 13, 14 or 15 bands depending on the complex. These bands exhibit variations in both frequency and molar absorptivity which are consistent with the nature of the equatorial ligands in the equatorial plane about the UO22+ axis being of major importance in determining the nature of the spectra. The overall influence of the equatorial ligands on the dioxouranium(VI) spectra appears to be determined by the combined effects of stereochemistry and ligand electron-donating ability.
