CeAgGa3 crystallizes in the tetragonal I-4m2 space group. Ce(1) is bonded in a 16-coordinate geometry to four equivalent Ag(1), four equivalent Ga(2), and eight equivalent Ga(1) atoms. Ag(1) is bonded to four equivalent Ce(1), four equivalent Ga(1), and four equivalent Ga(2) atoms to form distorted AgCe4Ga8 cuboctahedra that share corners with four equivalent Ga(2)Ce4Ga4Ag4 cuboctahedra, corners with twelve equivalent Ag(1)Ce4Ga8 cuboctahedra, edges with two equivalent Ga(2)Ce4Ga4Ag4 cuboctahedra, faces with four equivalent Ag(1)Ce4Ga8 cuboctahedra, and faces with four equivalent Ga(2)Ce4Ga4Ag4 cuboctahedra. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 9-coordinate geometry to four equivalent Ce(1), two equivalent Ag(1), one Ga(1), and two equivalent Ga(2) atoms. In the second Ga site, Ga(2) is bonded to four equivalent Ce(1), four equivalent Ag(1), and four equivalent Ga(1) atoms to form GaCe4Ga4Ag4 cuboctahedra that share corners with four equivalent Ag(1)Ce4Ga8 cuboctahedra, corners with twelve equivalent Ga(2)Ce4Ga4Ag4 cuboctahedra, edges with two equivalent Ag(1)Ce4Ga8 cuboctahedra, faces with four equivalent Ag(1)Ce4Ga8 cuboctahedra, and faces with four equivalent Ga(2)Ce4Ga4Ag4 cuboctahedra.
