Sr Fe Fe Cl
SrFe2Cl crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two SrFe2Cl clusters. Sr(1) is bonded in a single-bond geometry to one Fe(1) atom. The Sr(1)-Fe(1) bond length is 1.01 Å. There are two inequivalent Fe sites. In the first Fe site, Fe(1) is bonded in a 2-coordinate geometry to one Sr(1) and one Cl(1) atom. The Fe(1)-Cl(1) bond length is 2.26 Å. In the second Fe site, Fe(2) is bonded in a single-bond geometry to one Cl(1) atom. The Fe(2)-Cl(1) bond length is 0.26 Å. Cl(1) is bonded in a single-bond geometry to one Fe(1) and one Fe(2) atom.
