Rh3Ga5 is Magnesium tetraboride-like structured and crystallizes in the triclinic P-1 space group. There are three inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 8-coordinate geometry to one Ga(2), one Ga(3), one Ga(5), two equivalent Ga(1), and three equivalent Ga(4) atoms. In the second Rh site, Rh(2) is bonded in a 8-coordinate geometry to one Ga(5), two equivalent Ga(3), two equivalent Ga(4), and three equivalent Ga(2) atoms. In the third Rh site, Rh(3) is bonded in a 8-coordinate geometry to one Ga(4), two equivalent Ga(1), two equivalent Ga(3), and three equivalent Ga(5) atoms. There are five inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 4-coordinate geometry to two equivalent Rh(1) and two equivalent Rh(3) atoms. In the second Ga site, Ga(2) is bonded in a 4-coordinate geometry to one Rh(1) and three equivalent Rh(2) atoms. In the third Ga site, Ga(3) is bonded in a 5-coordinate geometry to one Rh(1), two equivalent Rh(2), and two equivalent Rh(3) atoms. In the fourth Ga site, Ga(4) is bonded in a 6-coordinate geometry to one Rh(3), two equivalent Rh(2), and three equivalent Rh(1) atoms. In the fifth Ga site, Ga(5) is bonded in a 5-coordinate geometry to one Rh(1), one Rh(2), and three equivalent Rh(3) atoms.
