The strong oxidising capacity of thallium(III) dominates its reaction with solutions of dithizone (H2Dz) in organic solvents. When carbon tetrachloride is used as solvent, the unstable thallium(III) complex Tl(HDz)3 is found in the organic phase but

The stability constant for the formation of EuCl2+ has been measured both by using a solid cation exchange resin and with a liquid cation exchanger and found to be 0·95 ± 0·15 at 20 ± 2°C and μ = 1·0 M. The evidence for higher complexes has be
