HoTi2ZnO6 crystallizes in the orthorhombic Pmn2_1 space group. Ho(1) is bonded in a 8-coordinate geometry to one O(1), one O(4), two equivalent O(2), and four equivalent O(3) atoms. Ti(1) is bonded to one O(1), one O(4), two equivalent O(2), and two equivalent O(3) atoms to form corner-sharing TiO6 octahedra. The corner-sharing octahedral tilt angles range from 34-42°. Zn(1) is bonded in a 4-coordinate geometry to one O(1), one O(4), and two equivalent O(3) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to one Ho(1), two equivalent Ti(1), and one Zn(1) atom. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to one Ho(1) and two equivalent Ti(1) atoms. In the third O site, O(3) is bonded in a 5-coordinate geometry to two equivalent Ho(1), two equivalent Ti(1), and one Zn(1) atom. In the fourth O site, O(4) is bonded in a tetrahedral geometry to one Ho(1), two equivalent Ti(1), and one Zn(1) atom.
