Mass spectrometric identification of cadmium(II) chlorobromide

Abstract

Mass spectrometric studies above solid CdCl₂ + CdBr₂ mixtures in the temperature range 720-770 K have revealed the existence of "mixed halide" gaseous species of formula CdClBr. The heat of formation of CdClBr(g) from CdCl₂(g) and CdBr₂(g) has been found to be 0.4 ± 1 kcal/mol. It is reasoned that the driving force for "mixed halide" formation is associated with a decrease in molecular symmetry.
