MnGa6 crystallizes in the orthorhombic Cmcm space group. Mn(1) is bonded in a distorted q6 geometry to two equivalent Ga(2), four equivalent Ga(1), and four equivalent Ga(3) atoms. There are three inequivalent Ga sites. In the first Ga site, Ga(2) is bonded in a 11-coordinate geometry to one Mn(1), two equivalent Ga(2), four equivalent Ga(1), and four equivalent Ga(3) atoms. In the second Ga site, Ga(1) is bonded in a 11-coordinate geometry to two equivalent Mn(1), one Ga(1), four equivalent Ga(2), and four equivalent Ga(3) atoms. In the third Ga site, Ga(3) is bonded in a 11-coordinate geometry to two equivalent Mn(1), one Ga(3), four equivalent Ga(1), and four equivalent Ga(2) atoms.
MnGa6 crystallizes in the orthorhombic Cmcm space group. Mn(1) is bonded in a distorted q6 geometry to two equivalent Ga(2), four equivalent Ga(1), and four equivalent Ga(3) atoms. Both Mn(1)-Ga(2) bond lengths are 2.47 Å. All Mn(1)-Ga(1) bond lengths are 2.61 Å. There are two shorter (2.57 Å) and two longer (2.68 Å) Mn(1)-Ga(3) bond lengths. There are three inequivalent Ga sites. In the first Ga site, Ga(2) is bonded in a 11-coordinate geometry to one Mn(1), two equivalent Ga(2), four equivalent Ga(1), and four equivalent Ga(3) atoms.
