Abstract

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.
