The material structure described by EuHSO5 crystallizes in the monoclinic P2_1/c space group. Eu(1) is bonded in a 9-coordinate geometry to one O(3), one O(5), two equivalent O(1), two equivalent O(2), and three equivalent O(4) atoms. H(1) is bonded in a single-bond geometry to one O(4) atom. S(1) is bonded in a tetrahedral geometry to one O(1), one O(2), one O(3), and one O(5) atom. There are five inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to two equivalent Eu(1) and one S(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to two equivalent Eu(1) and one S(1) atom. In the third O site, O(3) is bonded in a bent 150 degrees geometry to one Eu(1) and one S(1) atom. In the fourth O site, O(4) is bonded in a single-bond geometry to three equivalent Eu(1) and one H(1) atom. In the fifth O site, O(5) is bonded in a distorted single-bond geometry to one Eu(1) and one S(1) atom. is represented by the CIF file [CIF]
