The compound described by EuSeO3Cl crystallizes in the orthorhombic Pnma space group. Eu(1) is bonded to one O(2), four equivalent O(1), and two equivalent Cl(1) atoms to form a mixture of corner and edge-sharing EuCl2O5 pentagonal bipyramids. Se(1) is bonded in a 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 3-coordinate geometry to two equivalent Eu(1) and one Se(1) atom. In the second O site, O(2) is bonded in a bent 150 degrees geometry to one Eu(1) and one Se(1) atom. Cl(1) is bonded in a bent 150 degrees geometry to two equivalent Eu(1) atoms. is represented by the CIF file [CIF]
