Bismuth chloride is an inorganic compound with the chemical formula BiCl3. A common source of the Bi3+ ion, BiCl3 is generated by treating the oxide Bi2O3 with hydrochloric acid. In the gas phase, the species adopts a pyramidal structure, in accord with VSEPR theory. In contrast to the usual expectation by consistent with periodic trends, BiCl3 is Lewis acidic, forming a variety of chloro complexes such as [BiCl6] 3- that strongly violates the octet rule. Furthermore the octahedral structure of this complex does not follow the predictions of VSEPR theory. The dianionic complex [BiCl5] 2- does however adopt the expected square pyramidal structure. [Holleman, A. F.; Wiberg, E. "Inorganic Chemistry" Academic Press: San Diego, 2001. ISBN 0-12-352651-5.]

Uses

Bismuth chloride is an excellent water soluble crystalline source of bismuth. Its aqueous solution conducts electricity as does the molten material.
