Azido complexes of Tl(III) have been investigated colorimetrically. The results show the presence of three stable species in solution having the structures [Tl(N 3 ) 6 ] 3− , [Tl(N 3 ) 4 Cl 2 ] 3− and [Tl(N 3 ) 2 Cl 4 ] 3− . The complexes posses bright yellow colour in aqueous solution, are stable between a pH range 4.0–4.4 and are inextractable by organic solvents such as ethylacetate, ether, benzene, or carbon tetrachloride. Attempts to isolate these in the crystalline state resulted in their hydrolysis.
