Lu3(MnGa2)2 crystallizes in the hexagonal P-62m space group. Lu(1) is bonded in a 11-coordinate geometry to four equivalent Mn(1), one Ga(2), and six equivalent Ga(1) atoms. Mn(1) is bonded in a 9-coordinate geometry to six equivalent Lu(1) and three equivalent Ga(1) atoms. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 10-coordinate geometry to six equivalent Lu(1), two equivalent Mn(1), and two equivalent Ga(2) atoms. In the second Ga site, Ga(2) is bonded in a 9-coordinate geometry to three equivalent Lu(1) and six equivalent Ga(1) atoms.
Lu3(MnGa2)2 crystallizes in the hexagonal P-62m space group. Lu(1) is bonded in a 11-coordinate geometry to four equivalent Mn(1), one Ga(2), and six equivalent Ga(1) atoms. All Lu(1)-Mn(1) bond lengths are 2.93 Å. The Lu(1)-Ga(2) bond length is 2.86 Å. There are two shorter (3.04 Å) and four longer (3.13 Å) Lu(1)-Ga(1) bond lengths. Mn(1) is bonded in a 9-coordinate geometry to six equivalent Lu(1) and three equivalent Ga(1) atoms. All Mn(1)-Ga(1) bond lengths are 2.68 Å. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 10-coordinate geometry to six equivalent Lu(1), two equivalent Mn(1), and two equivalent Ga(2) atoms. Both Ga(1)-Ga(2) bond lengths are 2.80 Å. In the second Ga site, Ga(2) is bonded in a 9-coordinate geometry to three equivalent Lu(1) and six equivalent Ga(1) atoms.
