The material structure described by MgHoGa crystallizes in the hexagonal P-62m space group. Mg(1) is bonded to two equivalent Ga(1) and two equivalent Ga(2) atoms to form a mixture of distorted corner and edge-sharing MgGa4 tetrahedra. Ho(1) is bonded in a 5-coordinate geometry to one Ga(2) and four equivalent Ga(1) atoms. There are two inequivalent Ga sites. In the first Ga site, Ga(2) is bonded in a 9-coordinate geometry to six equivalent Mg(1) and three equivalent Ho(1) atoms. In the second Ga site, Ga(1) is bonded in a 9-coordinate geometry to three equivalent Mg(1) and six equivalent Ho(1) atoms. is represented by the CIF card [CIF]
