The caesium chloride structure adopts a primitive cubic lattice with a two-atom basis, where both atoms have eightfold coordination. The chloride atoms lie upon the lattice points at the corners of the cube, while the caesium atoms lie in the holes in the center of the cubes; an alternative and exactly equivalent 'setting' has the caesium ions at the corners and the chloride ion in the center. This structure is shared with CsBr and CsI and many binary metallic alloys. In contrast, the other al… WebJan 22, 2024 · CsCl can be thought of as two interpenetrating simple cubic arrays where the corner of one cell sits at the body center of the other. As with NaCl , the 1:1 stoichiometry means that the cell will look the same …
