The crystal structure described by Ho(MnGa)6 crystallizes in the orthorhombic Fmmm space group. Ho(1) is bonded in a 20-coordinate geometry to four equivalent Mn(1), four equivalent Mn(2), four equivalent Ga(2), and eight equivalent Ga(1) atoms. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in a 12-coordinate geometry to two equivalent Ho(1), two equivalent Mn(1), four equivalent Mn(2), and four equivalent Ga(1) atoms. In the second Mn site, Mn(2) is bonded in a 14-coordinate geometry to one Ho(1), two equivalent Mn(1), five equivalent Mn(2), two equivalent Ga(2), and four equivalent Ga(1) atoms. There are two inequivalent Ga sites. In the first Ga site, Ga(2) is bonded to two equivalent Ho(1), four equivalent Mn(2), two equivalent Ga(2), and four equivalent Ga(1) atoms to form a mixture of distorted face and corner-sharing GaHo2Mn4Ga6 cuboctahedra. In the second Ga site, Ga(1) is bonded in a 10-coordinate geometry to two equivalent Ho(1), two equivalent Mn(1), four equivalent Mn(2), and two equivalent Ga(2) atoms. is represented by the CIF card [CIF]
