Na(1) is bonded in a 5-coordinate geometry to one O(2), one O(7), two equivalent O(4), and two equivalent O(5) atoms. Co(1) is bonded to one O(1), one O(3), one O(4), one O(5), one O(6), and one O(8) atom to form distorted edge-sharing CoO6 octahedra. There are three inequivalent H sites. In the first H site, H(1) is bonded in a bent 120 degrees geometry to two equivalent O(5) atoms. In the second H site, H(2) is bonded in a single-bond geometry to one O(1) and one O(8) atom. In the third H site, H(3) is bonded in a bent 120 degrees geometry to two equivalent O(4) atoms. There are two inequivalent S sites. In the first S site, S(1) is bonded in a distorted L-shaped geometry to two equivalent O(5) atoms. In the second S site, S(2) is bonded in a distorted L-shaped geometry to two equivalent O(4) atoms. There are eight inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to two equivalent Co(1), one H(2), and one O(7) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to one Na(1) and one O(8) atom.
