In the gas phase and in the crystal, the species adopts a pyramidal structure, in accord with VSEPR theory. ==Preparation== Bismuth chloride can be synthesized directly by passing chlorine over bismuth. :2 Bi + 3 Cl2 → 2 BiCl3 or by dissolving bismuth metal in aqua regia, evaporating the mixture to give BiCl3.2H2O, which can be distilled to form the anhydrous trichloride. Alternatively, it may be prepared by adding hydrochloric acid to bismuth oxide and evaporating the solution. :Bi2O3 + 6 HCl → 2 BiCl3 + 3 H2O Also, the compound can be prepared by dissolving bismuth in concentrated nitric acid and then adding solid sodium chloride into this solution.〔Pradyot Patnaik.
