The compound described by In3Ga is alpha La-derived structured and crystallizes in the tetragonal I4/mmm space group. There are two inequivalent In sites. In the first In site, In(1) is bonded to four equivalent In(1), four equivalent In(2), and four equivalent Ga(1) atoms to form InIn8Ga4 cuboctahedra that share corners with twelve equivalent In(1)In8Ga4 cuboctahedra, edges with eight equivalent In(1)In8Ga4 cuboctahedra, edges with eight equivalent In(2)In8Ga4 cuboctahedra, edges with eight equivalent Ga(1)In12 cuboctahedra, faces with four equivalent In(2)In8Ga4 cuboctahedra, faces with four equivalent Ga(1)In12 cuboctahedra, and faces with ten equivalent In(1)In8Ga4 cuboctahedra. In the second In site, In(2) is bonded to eight equivalent In(1) and four equivalent Ga(1) atoms to form InIn8Ga4 cuboctahedra that share corners with four equivalent In(2)In8Ga4 cuboctahedra, corners with eight equivalent Ga(1)In12 cuboctahedra, edges with eight equivalent In(2)In8Ga4 cuboctahedra, edges with sixteen equivalent In(1)In8Ga4 cuboctahedra, faces with four equivalent In(2)In8Ga4 cuboctahedra, faces with six equivalent Ga(1)In12 cuboctahedra, and faces with eight equivalent In(1)In8Ga4 cuboctahedra.
