The material described by La2Cu3Ga5 crystallizes in the tetragonal P-4m2 space group. La(1) is bonded in a 16-coordinate geometry to two equivalent Cu(1), two equivalent Cu(2), two equivalent Cu(3), two equivalent Ga(3), four equivalent Ga(1), and four equivalent Ga(2) atoms. There are three inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a 8-coordinate geometry to four equivalent La(1) and four equivalent Ga(2) atoms. In the second Cu site, Cu(2) is bonded to four equivalent La(1), four equivalent Ga(1), and four equivalent Ga(3) atoms to form distorted CuLa4Ga8 cuboctahedra that share corners with four equivalent Cu(2)La4Ga8 cuboctahedra, faces with four equivalent Cu(2)La4Ga8 cuboctahedra, and faces with four equivalent Ga(3)La4Ga4Cu4 cuboctahedra. In the third Cu site, Cu(3) is bonded in a 8-coordinate geometry to four equivalent La(1) and four equivalent Ga(2) atoms. There are three inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 9-coordinate geometry to four equivalent La(1), two equivalent Cu(2), one Ga(2), and two equivalent Ga(3) atoms. In the second Ga site, Ga(2) is bonded in a 9-coordinate geometry to four equivalent La(1), two equivalent Cu(1), two equivalent Cu(3), and one Ga(1) atom. In the third Ga site, Ga(3) is bonded to four equivalent La(1), four equivalent Cu(2), and four equivalent Ga(1) atoms to form GaLa4Ga4Cu4 cuboctahedra that share corners with four equivalent Ga(3)La4Ga4Cu4 cuboctahedra, faces with four equivalent Cu(2)La4Ga8 cuboctahedra, and faces with four equivalent Ga(3)La4Ga4Cu4 cuboctahedra. is represented by the CIF file [CIF]
