Chromium(III) chloride (also called chromic chloride) describes any of several chemical compounds with the formula CrCl3 · x H2O, where x can be 0, 5, and 6. The anhydrous compound with the formula CrCl3 is a violet solid. The most common form of the trichloride is the dark green hexahydrate, CrCl3 · 6 … See more Anhydrous chromium(III) chloride adopts the YCl3 structure, with Cr occupying one third of the octahedral interstices in alternating layers of a pseudo-cubic close packed lattice of Cl ions. The absence of cations in alternate … See more Slow reaction rates are common with chromium(III) complexes. The low reactivity of the d Cr ion can be explained using crystal field theory. One way of opening CrCl3 up to substitution in solution is to reduce even a trace amount to CrCl2, for … See more • Handbook of Chemistry and Physics, 71st edition, CRC Press, Ann Arbor, Michigan, 1990. • The Merck Index, 7th edition, Merck & Co, Rahway, New Jersey, USA, 1960. • J.
