Sr Cr Cr Sb
SrCr2Sb crystallizes in the triclinic P1 space group. Sr(1) is bonded in a 4-coordinate geometry to two equivalent Cr(1) and two equivalent Sb(1) atoms. There is one shorter (2.56 Å) and one longer (2.87 Å) Sr(1)-Cr(1) bond length. There is one shorter (1.68 Å) and one longer (2.23 Å) Sr(1)-Sb(1) bond length. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded in a 2-coordinate geometry to two equivalent Sr(1) and one Cr(2) atom. The Cr(1)-Cr(2) bond length is 2.55 Å. In the second Cr site, Cr(2) is bonded in a 3-coordinate geometry to one Cr(1) and two equivalent Sb(1) atoms. There is one shorter (3.13 Å) and one longer (3.39 Å) Cr(2)-Sb(1) bond length. Sb(1) is bonded in a distorted bent 120 degrees geometry to two equivalent Sr(1) and two equivalent Cr(2) atoms.
