Sr Fe Fe Sb
SrFe2Sb crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one SrFe2Sb cluster. Sr(1) is bonded in a distorted single-bond geometry to one Fe(2) and one Sb(1) atom. The Sr(1)-Fe(2) bond length is 0.06 Å. The Sr(1)-Sb(1) bond length is 1.96 Å. There are two inequivalent Fe sites. In the first Fe site, Fe(1) is bonded in a distorted single-bond geometry to one Sb(1) atom. The Fe(1)-Sb(1) bond length is 2.01 Å. In the second Fe site, Fe(2) is bonded in a single-bond geometry to one Sr(1) atom. Sb(1) is bonded in a distorted linear geometry to one Sr(1) and one Fe(1) atom.
