In In Pt Pb
PtIn2Pb crystallizes in the triclinic P1 space group. Pt(1) is bonded in a distorted single-bond geometry to one In(2) and one Pb(1) atom. The Pt(1)-In(2) bond length is 1.30 Å. The Pt(1)-Pb(1) bond length is 2.42 Å. There are two inequivalent In sites. In the first In site, In(1) is bonded to one In(2), four equivalent In(1), and one Pb(1) atom to form distorted InIn5Pb octahedra that share corners with four equivalent In(1)In5Pb octahedra, edges with four equivalent In(1)In5Pb octahedra, and edges with four equivalent Pb(1)InPtPb4 octahedra. The corner-sharing octahedra are not tilted. The In(1)-In(2) bond length is 2.14 Å. All In(1)-In(1) bond lengths are 3.34 Å. The In(1)-Pb(1) bond length is 3.37 Å. In the second In site, In(2) is bonded in a distorted single-bond geometry to one Pt(1) and one In(1) atom. Pb(1) is bonded to one Pt(1), one In(1), and four equivalent Pb(1) atoms to form distorted PbInPtPb4 octahedra that share corners with four equivalent Pb(1)InPtPb4 octahedra, edges with four equivalent In(1)In5Pb octahedra, and edges with four equivalent Pb(1)InPtPb4 octahedra. The corner-sharing octahedra are not tilted. All Pb(1)-Pb(1) bond lengths are 3.34 Å.
