The work contained in this thesis describes the crystal and molecular structures of a number of uranium(VI) compounds, and the preparation of two of the neptunium(VI) analogues. Apparent from the results is the invariance of the uranyl U=0 bond length to substitution of sulphur or nitrogen for oxygen as the equatorial donor atom. This area has been explored through the determination of the following crystal structures: a) The dithiocarbarnate complexes [Et4N][UO2(C5H8NS2)3]; [Et4N][UO2(C7H10NS2)3]; [Et4N][UO2(C5H10NS2)3]; and [Me4N][UO2(C3H6NS2)3]. b) The pentane 2,4-dionate complexes [UO2(C6H5COCHCOC4H5)7(C5H5N)] and UO2(CH3COCHCOOC(CH3)3)2(C5H5N)] c) The bispyridyl bis nitrato complex [UO2(C5H5N)2)(NO3)2 In addition, the structures are described of the 1,10-Phenanthroline complex of uranyl acetate, and two unexpected products, [Ph4A5][(C4HN2S2)2] and [(Me2C4HN2S)2], obtained by ligand dimerisation whilst attempting to form U-S bonded species.
