The crystal structure described by HoZn(NiO3)2 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. Ni(1) is bonded to one O(1), one O(4), two equivalent O(2), and two equivalent O(3) atoms to form corner-sharing NiO6 octahedra. The corner-sharing octahedral tilt angles range from 36-43°. Zn(1) is bonded in a 6-coordinate geometry to one O(1), one O(4), two equivalent O(2), and two equivalent O(3) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded to one Ho(1), two equivalent Ni(1), and one Zn(1) atom to form a mixture of distorted corner and edge-sharing OHoZnNi2 trigonal pyramids. In the second O site, O(2) is bonded to one Ho(1), two equivalent Ni(1), and one Zn(1) atom to form a mixture of distorted corner and edge-sharing OHoZnNi2 trigonal pyramids. In the third O site, O(3) is bonded in a 5-coordinate geometry to two equivalent Ho(1), two equivalent Ni(1), and one Zn(1) atom. In the fourth O site, O(4) is bonded to one Ho(1), two equivalent Ni(1), and one Zn(1) atom to form distorted corner-sharing OHoZnNi2 trigonal pyramids. is represented by the Crystallographic Information File (CIF) [CIF]
