摘要：

At ambient conditions the hydrolysis of BiCl3 to BiOCl proceeds via the intermediate hydrate BiCl3 center dot H2O 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 degrees C the topochemical formation of the hydrate can be reversed by reducing the H2O vapour pressure. Above this temperature the hydrate is unstable and the mechanism of the hydrolysis changes. BiCl3 center dot H2O crystallizes in the monoclinic space group C2/m with lattice parameters a = 1114.25(1) pm, b = 876.82(1) pm, c = 584.20(1) pm, and beta = 106.64(1)degrees.
