Abstract

PbIn1 crystallizes in the trigonal R-3m space group. The structure is three-dimensional. there are three inequivalent In sites. In the first In site, In is bonded to six equivalent Pb atoms to form distorted InPb6 cuboctahedra that share corners with six InPb6 cuboctahedra, corners with twelve equivalent PbIn6Pb6 cuboctahedra, edges with twelve InPb6 cuboctahedra, and edges with twelve equivalent PbIn6Pb6 cuboctahedra. All In–Pb bond lengths are 3.49 Å. In the second In site, In is bonded to six Pb atoms to form distorted InPb6 cuboctahedra that share corners with six InPb6 cuboctahedra, corners with fourteen PbIn6Pb6 cuboctahedra, edges with twelve InPb6 cuboctahedra, edges with fourteen PbIn6Pb6 cuboctahedra, and faces with two equivalent PbIn6Pb10 cuboctahedra. All In–Pb bond lengths are 3.49 Å. In the third In site, In is bonded to six Pb atoms to form distorted InPb6 cuboctahedra that share corners with six InPb6 cuboctahedra, corners with fourteen PbIn6Pb6 cuboctahedra, edges with twelve InPb6 cuboctahedra, edges with fourteen PbIn6Pb6 cuboctahedra, and faces with two equivalent PbIn6Pb10 cuboctahedra. All In–Pb bond lengths are 3.49 Å. There are two inequivalent Pb sites. In the first Pb site, Pb is bonded to six In and six equivalent Pb atoms to form distorted PbIn6Pb6 cuboctahedra that share corners with twelve InPb6 cuboctahedra, corners with twelve PbIn6Pb6 cuboctahedra, edges with twelve InPb6 cuboctahedra, edges with twelve PbIn6Pb6 cuboctahedra, and faces with six equivalent PbIn6Pb6 cuboctahedra. All Pb–Pb bond lengths are 3.51 Å. In the second Pb site, Pb is bonded to six In and ten equivalent Pb atoms to form distorted PbIn6Pb10 cuboctahedra that share corners with twelve PbIn6Pb6 cuboctahedra, corners with sixteen InPb6 cuboctahedra, edges with sixteen InPb6 cuboctahedra, edges with sixteen PbIn6Pb6 cuboctahedra, faces with four InPb6 cuboctahedra, and faces with sixteen equivalent PbIn6Pb10 cuboctahedra. There are a spread of Pb–Pb bond distances ranging from 3.51–7.02 Å.
