The material described by HoTaO4 crystallizes in the monoclinic C2/c space group. Ho(1) is bonded in a 8-coordinate geometry to four equivalent O(1) and four equivalent O(2) atoms. Ta(1) is bonded in a 6-coordinate geometry to two equivalent O(2) and four equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Ho(1) and two equivalent Ta(1) atoms to form a mixture of distorted corner and edge-sharing OHo2Ta2 tetrahedra. In the second O site, O(2) is bonded in a distorted trigonal non-coplanar geometry to two equivalent Ho(1) and one Ta(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
