Coordination compounds of indium. Part XXXIII. X-Ray photoelectron spectroscopy of neutral and anionic indium halide species

The X-ray photoelectron spectra (metal and halogen energy levels) have been recorded for binary halides of indium in the +I, +II, and +III states, and for anionic halide complexes of indium(I) and (III). The results are internally consistent in terms of the relation between metal and ligand levels, but lattice effects prevent any detailed interpretation of indium levels in terms of oxidation state, ligand electronegativity, and/or coordination number.
