Materials Data on In3Ag by Materials Project

Abstract

AgIn3 is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Ag is bonded to twelve equivalent In atoms to form AgIn12 cuboctahedra that share corners with six equivalent AgIn12 cuboctahedra, corners with twelve equivalent InIn8Ag4 cuboctahedra, edges with eighteen equivalent InIn8Ag4 cuboctahedra, faces with eight equivalent AgIn12 cuboctahedra, and faces with twelve equivalent InIn8Ag4 cuboctahedra. There are six shorter (3.24 Å) and six longer (3.29 Å) Ag–In bond lengths. In is bonded to four equivalent Ag and eight equivalent In atoms to form InIn8Ag4 cuboctahedra that share corners with four equivalent AgIn12 cuboctahedra, corners with fourteen equivalent InIn8Ag4 cuboctahedra, edges with six equivalent AgIn12 cuboctahedra, edges with twelve equivalent InIn8Ag4 cuboctahedra, faces with four equivalent AgIn12 cuboctahedra, and faces with sixteen equivalent InIn8Ag4 cuboctahedra. There are a spread of In–In bond distances ranging from 3.19–3.38 Å.
