Abstract
ISOTOPIC exchange by electron transfer between complex ions containing an element in different oxidation states has been demonstrated for quite a number of elements. In some instances, such as: 
the exchange is so rapid as to seem instantaneous1. Systems containing an element in two oxidation states sometimes exhibit abnormally deep and intense colorations. For example, crystals of (NH4)2SbCl6, which are believed to contain the complex ions [SbCl6]3− and [SbCl6]−, are jet black2. The coloration of both solid (NH4)2SbCl6 and its solutions is so much more intense than that produced by the component complex ions separately that it is described as arising from interaction absorption.
