Materials Data on TmAg3 by Materials Project

Abstract

TmAg3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Tm is bonded to twelve equivalent Ag atoms to form TmAg12 cuboctahedra that share corners with twelve equivalent TmAg12 cuboctahedra, edges with twenty-four equivalent AgTm4Ag8 cuboctahedra, faces with six equivalent TmAg12 cuboctahedra, and faces with twelve equivalent AgTm4Ag8 cuboctahedra. All Tm–Ag bond lengths are 3.09 Å. Ag is bonded to four equivalent Tm and eight equivalent Ag atoms to form distorted AgTm4Ag8 cuboctahedra that share corners with twelve equivalent AgTm4Ag8 cuboctahedra, edges with eight equivalent TmAg12 cuboctahedra, edges with sixteen equivalent AgTm4Ag8 cuboctahedra, faces with four equivalent TmAg12 cuboctahedra, and faces with fourteen equivalent AgTm4Ag8 cuboctahedra. All Ag–Ag bond lengths are 3.09 Å.
