CrB is Tetraauricupride structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two chromium boride (crb) molecules. Cr(1) is bonded in a 1-coordinate geometry to one B(1) atom. The Cr(1)-B(1) bond length is 1.43 Å. B(1) is bonded in a 1-coordinate geometry to one Cr(1) atom.
