Dioxouranium salt

U04-2H20 reacts with hydrated dioxouranium(VI) oxalate, U02(C204)-H20 in the presence of aqueous alkali oxalate to form salts of peroxooxalato complex anions, M4[(U02)2(fi-02)(C204)4l (M1 = Na, K, Rb). Salts of the peroxocarbonato complex anion, [(U02)2(q-02)(C03)4], are obtained in a similar manner.234 Other reported salts of peroxooxalato and peroxocarbonato complex anions include M2[U02(02)(C204)] (M1 = Na, K, NH4),... [Pg.1193]

A selection of the known dioxouranium(VI) complexes with this type of ligand is given in Table 84. These compounds are precipitated from aqueous solution, usually after the addition of alkali. The coordination geometry of the anion in the ammonium salt of the cupferron complex, NH4[U02 (0N)N(Ph)0 3], is close to hexagonal bipyramidal.332... [Pg.1208]

Similarly, many tris(R-carbamate)dioxouranium(VI) complexes (exemplified by K[U02(Et2NCS2)3] H20) have been reported. The complexes are prepared by reacting uranyl acetate with the R-carbamate salt obtained by addition of R-amine to an aqueous solution containing equimolar amounts of carbon disulfide and potassium hydroxide. ... [Pg.293]
