Abstract

At ambient conditions the hydrolysis of BiCl~3~ to BiOCl proceeds via the intermediate hydrate BiCl~3~·H~2~O as has been revealed by time dependent in‐situ X‐ray powder diffraction as well as time and temperature controlled TG‐MS experiments. Below 50 °C the topochemical formation of thehydrate can be reversed by reducing the H~2~O vapour pressure. Above this temperature the hydrate is unstable and the mechanism of the hydrolysis changes. BiCl~3~·H~2~O crystallizes in the monoclinic space group __C__2/m with lattice parameters a = 1114.25(1) pm, b = 876.82(1) pm, c = 584.20(1) pm, and β = 106.64(1)°.
