BeGa3 is alpha bismuth trifluoride structured and crystallizes in the tetragonal I4/mmm space group. Be(1) is bonded to four equivalent Ga(2) and eight equivalent Ga(1) atoms to form BeGa12 cuboctahedra that share corners with four equivalent Be(1)Ga12 cuboctahedra, corners with eight equivalent Ga(2)Be4Ga8 cuboctahedra, edges with eight equivalent Be(1)Ga12 cuboctahedra, edges with sixteen equivalent Ga(1)Be4Ga8 cuboctahedra, faces with four equivalent Be(1)Ga12 cuboctahedra, faces with six equivalent Ga(2)Be4Ga8 cuboctahedra, and faces with eight equivalent Ga(1)Be4Ga8 cuboctahedra. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded to four equivalent Be(1), four equivalent Ga(1), and four equivalent Ga(2) atoms to form distorted GaBe4Ga8 cuboctahedra that share corners with twelve equivalent Ga(1)Be4Ga8 cuboctahedra, edges with eight equivalent Be(1)Ga12 cuboctahedra, edges with eight equivalent Ga(1)Be4Ga8 cuboctahedra, edges with eight equivalent Ga(2)Be4Ga8 cuboctahedra, faces with four equivalent Be(1)Ga12 cuboctahedra, faces with four equivalent Ga(2)Be4Ga8 cuboctahedra, and faces with ten equivalent Ga(1)Be4Ga8 cuboctahedra. In the second Ga site, Ga(2) is bonded to four equivalent Be(1) and eight equivalent Ga(1) atoms to form GaBe4Ga8 cuboctahedra that share corners with four equivalent Ga(2)Be4Ga8 cuboctahedra, corners with eight equivalent Be(1)Ga12 cuboctahedra, edges with eight equivalent Ga(2)Be4Ga8 cuboctahedra, edges with sixteen equivalent Ga(1)Be4Ga8 cuboctahedra, faces with four equivalent Ga(2)Be4Ga8 cuboctahedra, faces with six equivalent Be(1)Ga12 cuboctahedra, and faces with eight equivalent Ga(1)Be4Ga8 cuboctahedra.
