Co-ordination compounds of thallium(III). Part IV. Tetrahalogenothallate(III) anions of the type TIX4–nYn–, where Y = Br or I when X = Cl, and Y = I when X = Br
Abstract
The complexes (Et4N)TlX4–n, where Y = Br or I when X = Cl, and Y = I when X = Br, have been prepared and characterised by X-ray powder photography and electronic spectral measurements. Possible assignments for the electronic absorption bands are discussed.
