CsCl has a cubic structure that consists of an infinite chain of ions. The Cs (or Cl) ions sit at the eight corners of the cube and the Cl (or Cs) sit at the center of the cube (thus it is NOT a body-centered lattice since that requires the SAME ion to occupy the edges and center). The CN of both cation and anion is 8.

Complexes that share this structure include:
CsBr, CsI, TlCl, TlBr and under high pressure RbCl, RbBr, RbI.
Note that the difference between this and the fluorite structure is that alternate cations are missing in the fluorite lattice.
Information is available to show how the individual structural pages were created.
