In Sb Sb Pt
PtInSb2 crystallizes in the monoclinic Cm space group. Pt(1) is bonded in a single-bond geometry to one In(1) and one Sb(2) atom. The Pt(1)-In(1) bond length is 1.69 Å. The Pt(1)-Sb(2) bond length is 3.15 Å. In(1) is bonded in a distorted bent 120 degrees geometry to one Pt(1) and one Sb(1) atom. The In(1)-Sb(1) bond length is 1.83 Å. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a distorted single-bond geometry to one In(1) and one Sb(2) atom. The Sb(1)-Sb(2) bond length is 2.83 Å. In the second Sb site, Sb(2) is bonded to one Pt(1), one Sb(1), and four equivalent Sb(2) atoms to form a mixture of distorted corner and edge-sharing SbSb5Pt octahedra. The corner-sharing octahedra are not tilted. All Sb(2)-Sb(2) bond lengths are 3.39 Å.
