CaBr2 is Rutile structured and crystallizes in the tetragonal P4_2/mnm space group. Ca(1) is bonded to six equivalent Br(1) atoms to form a mixture of corner and edge-sharing CaBr6 octahedra. The corner-sharing octahedral tilt angles are 49°. Br(1) is bonded in a distorted trigonal planar geometry to three equivalent Ca(1) atoms.

The corner-sharing octahedral tilt angles are 49°. There are four shorter (2.90 Å) and two longer (2.91 Å) Ca(1)-Br(1) bond lengths. Br(1) is bonded in a distorted trigonal planar geometry to three equivalent Ca(1) atoms.
