Abstract

At ambient conditions the hydrolysis of BiCl3 to BiOCl proceeds via the intermediate hydrate: BiCl3-H2O as has been revealed by fimo dependent in-situ X-ray powdor diffraclion as well as time; and temperature controlled TG-MS experiments. Below 50 °C the topochemical formation of the hydrate can be reversed by reduciny the H2O vapour pressure. Above this temperature the hydrate is unstable and the mechanism of the hydrolysis changes. BiCl3·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 β = 106.64(1)°.
