The crystal structure described by Ho2NiMnO6 crystallizes in the monoclinic P2_1/c space group. Ho(1) is bonded in a 8-coordinate geometry to two equivalent O(1), three equivalent O(2), and three equivalent O(3) atoms. Mn(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form MnO6 octahedra that share corners with six equivalent Ni(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 34-37°. Ni(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form NiO6 octahedra that share corners with six equivalent Mn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 34-37°. There are three inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Ho(1), one Mn(1), and one Ni(1) atom to form distorted corner-sharing OHo2MnNi trigonal pyramids. In the second O site, O(2) is bonded in a 5-coordinate geometry to three equivalent Ho(1), one Mn(1), and one Ni(1) atom. In the third O site, O(3) is bonded in a 5-coordinate geometry to three equivalent Ho(1), one Mn(1), and one Ni(1) atom. is represented by the CIF card [CIF]
