       1.8.3 CsCl Structure

  • MX type compounds, parent compound being CsCl.

  • Examples: Halides such as CSCl,  AgI, AgBr etc.

  • Radius ratio governs cubic co-ordination of both cations and anions.

  • Lattice type: Primitive cubic lattice.

  • Motif: Anions (X): 0 0 0, Cations (M): ½ ½ ½

  • One formula unit per unit cell.
