The material described by TbSeO3Cl crystallizes in the orthorhombic Pnma space group. Tb(1) is bonded to one O(2), four equivalent O(1), and two equivalent Cl(1) atoms to form a mixture of distorted corner and edge-sharing TbCl2O5 pentagonal bipyramids. Se(1) is bonded in a distorted trigonal non-coplanar geometry to one O(2) and two equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to two equivalent Tb(1) and one Se(1) atom. In the second O site, O(2) is bonded in a bent 150 degrees geometry to one Tb(1) and one Se(1) atom. Cl(1) is bonded in a bent 150 degrees geometry to two equivalent Tb(1) atoms. is represented by the CIF card [CIF]
