Abstract

An Energy Dispersive X-ray Diffraction (EDXD) study of 0.3 m dioxouranium(VI) in 1 m lithium citrate at pH = 5 is reported. The data are in accordance with the existence of a predominately polynuclear complex contg. four U atoms, concluded from potentiometric measurements. The uranium atoms lie at the corners of two triangles sharing one edge. Five O atoms surround each uranyl group, the uranium coordination polyhedron being a pentagonal bipyramid; four U atoms are linked through double or single O bridges. The U-U distances are 3.95 .ANG. and 4.65 .ANG..
