The compound described by SrH2O7I2 crystallizes in the monoclinic C2/c space group. Sr(1) is bonded in a 7-coordinate geometry to one O(1), two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms. H(1) is bonded in a single-bond geometry to one O(1) atom. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted water-like geometry to one Sr(1) and two equivalent H(1) atoms. In the second O site, O(2) is bonded in a distorted bent 120 degrees geometry to one Sr(1) and one I(1) atom. In the third O site, O(3) is bonded in a 1-coordinate geometry to one Sr(1) and one I(1) atom. In the fourth O site, O(4) is bonded in a distorted bent 120 degrees geometry to one Sr(1) and one I(1) atom. I(1) is bonded in a distorted trigonal non-coplanar geometry to one O(2), one O(3), and one O(4) atom. is represented by the CIF card [CIF]
