The structure described by Na2CoH8(CO5)2 crystallizes in the monoclinic C2/c space group. Na(1) is bonded to one O(1), one O(2), two equivalent O(4), and two equivalent O(5) atoms to form edge-sharing NaO6 octahedra. Co(1) is bonded in a 6-coordinate geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms. C(1) is bonded in a trigonal planar geometry to one O(1), one O(2), and one O(3) atom. There are four inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one O(4) atom. In the second H site, H(2) is bonded in a single-bond geometry to one O(4) atom. In the third H site, H(3) is bonded in a single-bond geometry to one O(5) atom. In the fourth H site, H(4) is bonded in a single-bond geometry to one O(5) atom. There are five inequivalent O sites. In the first O site, O(4) is bonded in a distorted water-like geometry to two equivalent Na(1), one H(1), and one H(2) atom. In the second O site, O(5) is bonded in a distorted water-like geometry to two equivalent Na(1), one H(3), and one H(4) atom. In the third O site, O(1) is bonded in a 3-coordinate geometry to one Na(1), one Co(1), and one C(1) atom. In the fourth O site, O(2) is bonded in a 1-coordinate geometry to one Na(1), one Co(1), and one C(1) atom. In the fifth O site, O(3) is bonded in a 2-coordinate geometry to one Co(1) and one C(1) atom. is represented by the CIF card [CIF]
