Abstract
The halide salts of the dispositive NN′-dimethyl-4,4′-bipyridinium cation (Me2bipy,X2; X = Cl, Br, or I) react with indium monohalides to give salts of the trihalogenoindate(I) anions Me2bipy,InX3, in which the anion is iso-electronic with SnX3 – and SbX3. With indium trihalides the products are either Me2bipy,[InCl5] or Me2bipy2++ InX4 –+ X–(X = Br or I); the InCl5 2– anion has C4v symmetry in the salt prepared, and this result is discussed in terms of earlier studies of this anion. The indium dihalides yield a mixture of InI and InIII anions. The Raman spectra are reported for the anionic complexes prepared, for the indium monohalides, and for indium dibromide and di-iodide.Keywords
