Fe Fe Sb Pt
Fe2PtSb crystallizes in the monoclinic Cm space group. There are two inequivalent Fe sites. In the first Fe site, Fe(1) is bonded in a distorted single-bond geometry to one Pt(1) and one Sb(1) atom. The Fe(1)-Pt(1) bond length is 3.16 Å. The Fe(1)-Sb(1) bond length is 2.14 Å. In the second Fe site, Fe(2) is bonded in a single-bond geometry to one Pt(1) and one Sb(1) atom. The Fe(2)-Pt(1) bond length is 3.16 Å. The Fe(2)-Sb(1) bond length is 0.12 Å. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded to one Fe(1); one Fe(2); and six Pt(1,1) atoms to form a mixture of distorted edge and corner-sharing PtFe2Pt6 hexagonal bipyramids. All Pt(1)-Pt(1,1) bond lengths are 2.96 Å. In the second Pt site, Pt(1) is bonded to one Fe(1); one Fe(2); and six Pt(1,1) atoms to form a mixture of distorted edge and corner-sharing PtFe2Pt6 hexagonal bipyramids. The Pt(1)-Fe(1) bond length is 3.16 Å. The Pt(1)-Fe(2) bond length is 3.16 Å. Both Pt(1)-Pt(1) bond lengths are 2.96 Å. Sb(1) is bonded in a single-bond geometry to one Fe(1) and one Fe(2) atom.
