Cs2Sn(HO2)6 crystallizes in the trigonal P-3 space group. Cs(1) is bonded in a 9-coordinate geometry to three equivalent O(1) and six equivalent O(2) atoms. Sn(1) is bonded in an octahedral geometry to six equivalent O(1) atoms. H(1) is bonded in a distorted linear geometry to one O(1) and one O(2) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 2-coordinate geometry to one Cs(1), one Sn(1), and one H(1) atom. In the second O site, O(2) is bonded in a single-bond geometry to two equivalent Cs(1) and one H(1) atom.
