Sr Fe Fe P
SrFe2P is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two SrFe2P clusters. Sr(1) is bonded in a linear geometry to one Fe(1) and one P(1) atom. The Sr(1)-Fe(1) bond length is 0.82 Å. The Sr(1)-P(1) bond length is 0.66 Å. There are two inequivalent Fe sites. In the first Fe site, Fe(1) is bonded in a single-bond geometry to one Sr(1) atom. In the second Fe site, Fe(2) is bonded in a single-bond geometry to one P(1) atom. The Fe(2)-P(1) bond length is 0.08 Å. P(1) is bonded in a linear geometry to one Sr(1) and one Fe(2) atom.
