The material described by EuSO4 crystallizes in the orthorhombic Pnma space group. Eu(1) is bonded in a 10-coordinate geometry to one O(2), three equivalent O(3), and six equivalent O(1) atoms. S(1) is bonded in a tetrahedral geometry to one O(2), one O(3), and two equivalent O(1) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to three equivalent Eu(1) and one S(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to one Eu(1) and one S(1) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to three equivalent Eu(1) and one S(1) atom. is represented by the CIF card [CIF]
