The material structure described by Na4CO4 crystallizes in the cubic P-43m space group. Na(1) is bonded in a 6-coordinate geometry to six equivalent O(1) atoms. C(1) is bonded in a tetrahedral geometry to four equivalent O(1) atoms. O(1) is bonded in a distorted single-bond geometry to six equivalent Na(1) and one C(1) atom. is represented by the CIF file [CIF]
