(NaCO2)4H2 crystallizes in the orthorhombic P2_12_12 space group. The structure consists of two 1333-74-0 atoms inside a NaCO2 framework. In the NaCO2 framework, Na(1) is bonded in a 6-coordinate geometry to two equivalent O(1) and four equivalent O(2) atoms. C(1) is bonded in a distorted bent 120 degrees 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 distorted single-bond geometry to two equivalent Na(1) and one C(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to four equivalent Na(1) and one C(1) atom.

In the NaCO2 framework, Na(1) is bonded in a 6-coordinate geometry to two equivalent O(1) and four equivalent O(2) atoms. There is one shorter (2.41 Å) and one longer (2.72 Å) Na(1)-O(1) bond length. There are a spread of Na(1)-O(2) bond distances ranging from 2.43-2.88 Å. C(1) is bonded in a distorted bent 120 degrees geometry to one O(1) and one O(2) atom. The C(1)-O(1) bond length is 1.26 Å. The C(1)-O(2) bond length is 1.28 Å. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to two equivalent Na(1) and one C(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to four equivalent Na(1) and one C(1) atom.
