The material structure described by Ho2WO6 crystallizes in the orthorhombic P2_12_12_1 space group. There are two inequivalent Ho sites. In the first Ho site, Ho(1) is bonded in a 7-coordinate geometry to one O(2), one O(3), one O(4), one O(5), one O(6), and two equivalent O(1) atoms. In the second Ho site, Ho(2) is bonded to one O(2), one O(3), one O(4), two equivalent O(5), and two equivalent O(6) atoms to form distorted HoO7 hexagonal pyramids that share corners with three equivalent W(1)O6 octahedra, edges with two equivalent Ho(2)O7 hexagonal pyramids, and edges with two equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 39-46°. W(1) is bonded to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom to form WO6 octahedra that share corners with three equivalent Ho(2)O7 hexagonal pyramids and edges with two equivalent Ho(2)O7 hexagonal pyramids. There are six inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to two equivalent Ho(1) and one W(1) atom. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to one Ho(1), one Ho(2), and one W(1) atom. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to one Ho(1), one Ho(2), and one W(1) atom. In the fourth O site, O(4) is bonded in a distorted trigonal non-coplanar geometry to one Ho(1), one Ho(2), and one W(1) atom. In the fifth O site, O(5) is bonded to one Ho(1), two equivalent Ho(2), and one W(1) atom to form a mixture of distorted corner and edge-sharing OHo3W tetrahedra. In the sixth O site, O(6) is bonded to one Ho(1), two equivalent Ho(2), and one W(1) atom to form a mixture of corner and edge-sharing OHo3W tetrahedra. is represented by the CIF card [CIF]
