SrCr2B is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two SrCr2B clusters. Sr(1) is bonded in a distorted linear geometry to one Cr(1) and one B(1) atom. The Sr(1)-Cr(1) bond length is 1.47 Å. The Sr(1)-B(1) bond length is 0.28 Å. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded in a linear geometry to one Sr(1) and one Cr(2) atom. The Cr(1)-Cr(2) bond length is 0.68 Å. In the second Cr site, Cr(2) is bonded in a single-bond geometry to one Cr(1) atom. B(1) is bonded in a single-bond geometry to one Sr(1) atom.
