CsF reacts with Br 2 to form the two intercalation compounds CsF·Br 2 and 2CsF·Br 2 . The former consists of layers of CsF squares separated by layers of Br 2 molecules oriented perpendicular to the CsF layers. 2CsF·Br 2 is a second‐stage compound, composed of two layers of CsF followed by one layer of bromine molecules. Iodine cannot replace bromine; instead, it reacts with CsF to form Cs 2 I 8 , and probably CsIF 6 between 0° and 120 °C. Chlorine does not react at all with CsF. Bromine reacts with RbF only superficially, and after a long time some RbBr 3 is observed; RbF and I 2 give RbI 3 .
