The material described by CrB4 crystallizes in the orthorhombic Immm space group. Cr(1) is bonded to twelve equivalent B(1) atoms to form a mixture of edge and face-sharing CrB12 cuboctahedra. B(1) is bonded in a 7-coordinate geometry to three equivalent Cr(1) and four equivalent B(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
