Ag3Ga is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. Ag(1) is bonded to eight equivalent Ag(1) and four equivalent Ga(1) atoms to form AgGa4Ag8 cuboctahedra that share corners with four equivalent Ga(1)Ag12 cuboctahedra, corners with fourteen equivalent Ag(1)Ga4Ag8 cuboctahedra, edges with six equivalent Ga(1)Ag12 cuboctahedra, edges with twelve equivalent Ag(1)Ga4Ag8 cuboctahedra, faces with four equivalent Ga(1)Ag12 cuboctahedra, and faces with sixteen equivalent Ag(1)Ga4Ag8 cuboctahedra. Ga(1) is bonded to twelve equivalent Ag(1) atoms to form GaAg12 cuboctahedra that share corners with six equivalent Ga(1)Ag12 cuboctahedra, corners with twelve equivalent Ag(1)Ga4Ag8 cuboctahedra, edges with eighteen equivalent Ag(1)Ga4Ag8 cuboctahedra, faces with eight equivalent Ga(1)Ag12 cuboctahedra, and faces with twelve equivalent Ag(1)Ga4Ag8 cuboctahedra.

There are a spread of Ag(1)-Ag(1) bond distances ranging from 2.87-2.91 Å. There are two shorter (2.87 Å) and two longer (2.89 Å) Ag(1)-Ga(1) bond lengths. Ga(1) is bonded to twelve equivalent Ag(1) atoms to form GaAg12 cuboctahedra that share corners with six equivalent Ga(1)Ag12 cuboctahedra, corners with twelve equivalent Ag(1)Ga4Ag8 cuboctahedra, edges with eighteen equivalent Ag(1)Ga4Ag8 cuboctahedra, faces with eight equivalent Ga(1)Ag12 cuboctahedra, and faces with twelve equivalent Ag(1)Ga4Ag8 cuboctahedra.
