CrBr2 is zeta iron carbide structured and crystallizes in the tetragonal P4_2/mnm space group. Cr(1) is bonded to six equivalent Br(1) atoms to form a mixture of corner and edge-sharing CrBr6 octahedra. The corner-sharing octahedral tilt angles are 47°. Br(1) is bonded in a 3-coordinate geometry to three equivalent Cr(1) atoms.

Cr(1) is bonded to six equivalent Br(1) atoms to form a mixture of corner and edge-sharing CrBr6 octahedra. The corner-sharing octahedral tilt angles are 47°. There are four shorter (2.55 Å) and two longer (3.03 Å) Cr(1)-Br(1) bond lengths. Br(1) is bonded in a 3-coordinate geometry to three equivalent Cr(1) atoms.
