La2AuGa7 crystallizes in the tetragonal P4mm space group. There are two inequivalent La sites. In the first La site, La(1) is bonded in a 16-coordinate geometry to four equivalent Au(1), four equivalent Ga(1), four equivalent Ga(2), and four equivalent Ga(5) atoms. In the second La site, La(2) is bonded in a 16-coordinate geometry to four equivalent Ga(1), four equivalent Ga(2), four equivalent Ga(3), and four equivalent Ga(4) atoms. Au(1) is bonded in a 5-coordinate geometry to four equivalent La(1), one Ga(5), and four equivalent Ga(1) atoms. There are five inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a distorted bent 120 degrees geometry to two equivalent La(1), two equivalent La(2), two equivalent Au(1), and two equivalent Ga(4) atoms. In the second Ga site, Ga(2) is bonded in a 8-coordinate geometry to two equivalent La(1), two equivalent La(2), two equivalent Ga(3), and two equivalent Ga(5) atoms.
