✦ Synopsis
CsF reacts with Br, to form the two intercalation compounds CsF.Br, and 2CsF.Br2. The former consists of layers of CsF squares separated by layers of Br, molecules oriented perpendicular to the CsF layers. 2CsF.BrZ 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,I,, and probably CsIF, 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, is observed; RbF and I, give RbI,.
