Abstract
THERE is evidence for reaction between mixtures of pure anhydrous LiCl and CrCl3 when they are fused at between 500° and 700° C, and the resultant melts are cooled. An equation can be written This evidence consisted of the destruction of the characteristic purple, insoluble layer crystals of CrCl3 and the formation of a pink salt soluble in water. Reaction 1 is written in analogy to the reactions believed to occur in the NaCl–CrCl3 and the KCl–CrCl3 systems with fusion and cooling. Cook1 has reported the formation of Na3CrCl6 and K3CrCl6 in these systems. Such reactions can be regarded as depolymerizing reactions without change in either the covalence or oxidation state of the central metal atoms.
