The material structure described by Sr2CuH2(SeO3)4 crystallizes in the triclinic P-1 space group. Sr(1) is bonded in a 9-coordinate geometry to one O(1), one O(2), one O(5), one O(6), two equivalent O(3), and three equivalent O(4) atoms. Cu(1) is bonded in a square co-planar geometry to two equivalent O(5) and two equivalent O(6) atoms. H(1) is bonded in a single-bond geometry to one O(2) atom. There are two inequivalent Se sites. In the first Se site, Se(1) is bonded in a distorted trigonal non-coplanar geometry to one O(1), one O(2), and one O(3) atom. In the second Se site, Se(2) is bonded in a distorted trigonal non-coplanar geometry to one O(4), one O(5), and one O(6) atom. There are six inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one Sr(1) and one Se(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to one Sr(1), one H(1), and one Se(1) atom. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to two equivalent Sr(1) and one Se(1) atom. In the fourth O site, O(4) is bonded in a 4-coordinate geometry to three equivalent Sr(1) and one Se(2) atom. In the fifth O site, O(5) is bonded in a distorted trigonal non-coplanar geometry to one Sr(1), one Cu(1), and one Se(2) atom. In the sixth O site, O(6) is bonded in a distorted trigonal non-coplanar geometry to one Sr(1), one Cu(1), and one Se(2) atom. is represented by the CIF card [CIF]
