Materials Data on ZnPb3 by Materials Project

Abstract

ZnPb3 is beta-derived structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Zn is bonded to twelve equivalent Pb atoms to form distorted ZnPb12 cuboctahedra that share corners with six equivalent ZnPb12 cuboctahedra, corners with twelve equivalent PbZn4Pb8 cuboctahedra, edges with eighteen equivalent PbZn4Pb8 cuboctahedra, faces with eight equivalent ZnPb12 cuboctahedra, and faces with twelve equivalent PbZn4Pb8 cuboctahedra. There are six shorter (3.40 Å) and six longer (3.43 Å) Zn–Pb bond lengths. Pb is bonded to four equivalent Zn and eight equivalent Pb atoms to form distorted PbZn4Pb8 cuboctahedra that share corners with four equivalent ZnPb12 cuboctahedra, corners with fourteen equivalent PbZn4Pb8 cuboctahedra, edges with six equivalent ZnPb12 cuboctahedra, edges with twelve equivalent PbZn4Pb8 cuboctahedra, faces with four equivalent ZnPb12 cuboctahedra, and faces with sixteen equivalent PbZn4Pb8 cuboctahedra. There are a spread of Pb–Pb bond distances ranging from 3.35–3.52 Å.
