SrCr2Sb crystallizes in the monoclinic Cm space group. Sr(1) is bonded in a 13-coordinate geometry to four equivalent Sr(1), one Cr(2), four equivalent Cr(1), and four equivalent Sb(1) atoms. All Sr(1)-Sr(1) bond lengths are 3.21 Å. The Sr(1)-Cr(2) bond length is 3.07 Å. There are a spread of Sr(1)-Cr(1) bond distances ranging from 3.30-3.90 Å. There are a spread of Sr(1)-Sb(1) bond distances ranging from 3.10-3.74 Å. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded in a 2-coordinate geometry to four equivalent Sr(1), one Cr(2), and one Sb(1) atom. The Cr(1)-Cr(2) bond length is 1.82 Å. The Cr(1)-Sb(1) bond length is 2.49 Å. In the second Cr site, Cr(2) is bonded in a 1-coordinate geometry to one Sr(1) and one Cr(1) atom. Sb(1) is bonded in a 2-coordinate geometry to four equivalent Sr(1) and one Cr(1) atom.
