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.
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. There are four shorter (2.09 Å) and eight longer (2.20 Å) Cr(1)-B(1) bond lengths. B(1) is bonded in a 7-coordinate geometry to three equivalent Cr(1) and four equivalent B(1) atoms. There are a spread of B(1)-B(1) bond distances ranging from 1.72-1.85 Å.
