The material structure described by HoSeO3Cl crystallizes in the orthorhombic Pnma space group. Ho(1) is bonded to one O(1), four equivalent O(2), and two equivalent Cl(1) atoms to form a mixture of distorted corner and edge-sharing HoCl2O5 pentagonal bipyramids. Se(1) is bonded in a distorted trigonal non-coplanar geometry to one O(1) and two equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one Ho(1) and one Se(1) atom. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to two equivalent Ho(1) and one Se(1) atom. Cl(1) is bonded in a bent 150 degrees geometry to two equivalent Ho(1) atoms. is represented by the CIF file [CIF]
