New dioxouranium(VI) complexes with the dibasic terdentate Schiff bases, XC6H3(2-OH)CH=N-CH2C6H4(2?-OH) (X = H, 5-Cl or 3-MeO), have been synthesized and characterized as their 1 : 1 alcohol adducts. The labile alcohol molecules in these complexes are readily replaced by various oxygen or nitrogen donor ligands, affording six- or seven- coordinate complexes. Evidence is presented for the rather weak coordination of these Lewis bases to the uranium metal atom. The various possible conformations for these [6,6]-membered chelate complexes are also discussed.

Derivatives Of

Dioxouranium(VI) derivatives of the type UO2(NO3)2(SBH2)2 have been synthesised by the reactions of dioxouranium(VI) nitrate hexahydrate with the nitrogen donor ligands (SBH2) in 1: 2 molar ratio. The Schiff bases used in these reactions are of the general type, o-HOC6H4C(CH3): NX1OH (where X1 = -CH2CH2-, -CH2CH(CH3)- and -CH2CH2CH2-), CH3C(OH)CHC(CH3): NX2OH and o-OHC6H4CH: NX2OH (where X2 = -CH2CH2-, -CH2CH(CH3)-, -CH2CH2CH2- and o-C6H4). The resulting new derivatives have been characterized on the basis of elemental analysis, magnetic susceptibility, conductance measurements and infrared spectra
