The compound described by (Na)3(AlO2)4 crystallizes in the cubic Im-3m space group. The structure consists of twelve 7440-23-5 atoms inside a AlO2 framework. In the AlO2 framework, Al(1) is bonded to one O(2) and three equivalent O(1) atoms to form corner-sharing AlO4 tetrahedra. There are two inequivalent O sites. In the first O site, O(2) is bonded in a linear geometry to two equivalent Al(1) atoms. In the second O site, O(1) is bonded in a bent 150 degrees geometry to two equivalent Al(1) atoms. is represented by the CIF file [CIF]
