Materials Data on HoAgSn2 by Materials Project

Abstract

HoAgSn2 is Uranium Silicide-derived structured and crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. Ho is bonded to four equivalent Ag and eight equivalent Sn atoms to form HoAg4Sn8 cuboctahedra that share corners with twelve equivalent HoAg4Sn8 cuboctahedra, edges with eight equivalent AgHo4Sn8 cuboctahedra, edges with sixteen equivalent SnHo4Ag4Sn4 cuboctahedra, faces with four equivalent AgHo4Sn8 cuboctahedra, faces with six equivalent HoAg4Sn8 cuboctahedra, and faces with eight equivalent SnHo4Ag4Sn4 cuboctahedra. All Ho–Ag bond lengths are 3.28 Å. All Ho–Sn bond lengths are 3.20 Å. Ag is bonded to four equivalent Ho and eight equivalent Sn atoms to form AgHo4Sn8 cuboctahedra that share corners with twelve equivalent AgHo4Sn8 cuboctahedra, edges with eight equivalent HoAg4Sn8 cuboctahedra, edges with sixteen equivalent SnHo4Ag4Sn4 cuboctahedra, faces with four equivalent HoAg4Sn8 cuboctahedra, faces with six equivalent AgHo4Sn8 cuboctahedra, and faces with eight equivalent SnHo4Ag4Sn4 cuboctahedra. All Ag–Sn bond lengths are 3.20 Å. Sn is bonded to four equivalent Ho, four equivalent Ag, and four equivalent Sn atoms to form distorted SnHo4Ag4Sn4 cuboctahedra that share corners with twelve equivalent SnHo4Ag4Sn4 cuboctahedra, edges with eight equivalent HoAg4Sn8 cuboctahedra, edges with eight equivalent AgHo4Sn8 cuboctahedra, edges with eight equivalent SnHo4Ag4Sn4 cuboctahedra, faces with four equivalent HoAg4Sn8 cuboctahedra, faces with four equivalent AgHo4Sn8 cuboctahedra, and faces with ten equivalent SnHo4Ag4Sn4 cuboctahedra. All Sn–Sn bond lengths are 3.28 Å.
