FeAg3 is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. Fe(1) is bonded to twelve equivalent Ag(1) atoms to form FeAg12 cuboctahedra that share corners with six equivalent Fe(1)Ag12 cuboctahedra, corners with twelve equivalent Ag(1)Fe4Ag8 cuboctahedra, edges with eighteen equivalent Ag(1)Fe4Ag8 cuboctahedra, faces with eight equivalent Fe(1)Ag12 cuboctahedra, and faces with twelve equivalent Ag(1)Fe4Ag8 cuboctahedra. Ag(1) is bonded to four equivalent Fe(1) and eight equivalent Ag(1) atoms to form AgFe4Ag8 cuboctahedra that share corners with four equivalent Fe(1)Ag12 cuboctahedra, corners with fourteen equivalent Ag(1)Fe4Ag8 cuboctahedra, edges with six equivalent Fe(1)Ag12 cuboctahedra, edges with twelve equivalent Ag(1)Fe4Ag8 cuboctahedra, faces with four equivalent Fe(1)Ag12 cuboctahedra, and faces with sixteen equivalent Ag(1)Fe4Ag8 cuboctahedra.

There are six shorter (2.84 Å) and six longer (2.89 Å) Fe(1)-Ag(1) bond lengths. Ag(1) is bonded to four equivalent Fe(1) and eight equivalent Ag(1) atoms to form AgFe4Ag8 cuboctahedra that share corners with four equivalent Fe(1)Ag12 cuboctahedra, corners with fourteen equivalent Ag(1)Fe4Ag8 cuboctahedra, edges with six equivalent Fe(1)Ag12 cuboctahedra, edges with twelve equivalent Ag(1)Fe4Ag8 cuboctahedra, faces with four equivalent Fe(1)Ag12 cuboctahedra, and faces with sixteen equivalent Ag(1)Fe4Ag8 cuboctahedra. There are a spread of Ag(1)-Ag(1) bond distances ranging from 2.84-2.94 Å.
