The material structure described by HoCu(WO4)2 crystallizes in the monoclinic P2/c space group. Ho(1) is bonded to two equivalent O(1), two equivalent O(3), and two equivalent O(4) atoms to form HoO6 octahedra that share corners with eight equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 48-58°. W(1) is bonded to one O(1), one O(3), two equivalent O(2), and two equivalent O(4) atoms to form distorted WO6 octahedra that share corners with four equivalent Ho(1)O6 octahedra and edges with two equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 48-58°. Cu(1) is bonded in a 4-coordinate geometry to two equivalent O(1) and two equivalent O(2) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one Ho(1), one W(1), and one Cu(1) atom. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to two equivalent W(1) and one Cu(1) atom. In the third O site, O(3) is bonded in a distorted bent 120 degrees geometry to one Ho(1) and one W(1) atom. In the fourth O site, O(4) is bonded in a trigonal planar geometry to one Ho(1) and two equivalent W(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
