Abstract

Sm3Ag is Uranium Silicide-like structured and crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. there are two inequivalent Sm sites. In the first Sm site, Sm is bonded to eight Sm and four equivalent Ag atoms to form distorted SmSm8Ag4 cuboctahedra that share corners with twelve equivalent SmSm8Ag4 cuboctahedra, edges with eight equivalent SmSm8Ag4 cuboctahedra, edges with eight equivalent AgSm12 cuboctahedra, faces with four equivalent AgSm12 cuboctahedra, and faces with ten equivalent SmSm8Ag4 cuboctahedra. There are four shorter (3.34 Å) and four longer (3.50 Å) Sm–Sm bond lengths. All Sm–Ag bond lengths are 3.50 Å. In the second Sm site, Sm is bonded in a square co-planar geometry to eight equivalent Sm and four equivalent Ag atoms. All Sm–Ag bond lengths are 3.34 Å. Ag is bonded to twelve Sm atoms to form AgSm12 cuboctahedra that share corners with four equivalent AgSm12 cuboctahedra, edges with eight equivalent AgSm12 cuboctahedra, edges with sixteen equivalent SmSm8Ag4 cuboctahedra, faces with four equivalent AgSm12 cuboctahedra, and faces with eight equivalent SmSm8Ag4 cuboctahedra.
