The compound described by NaOsO3 crystallizes in the trigonal R-3c space group. Na(1) is bonded in a distorted trigonal planar geometry to nine equivalent O(1) atoms. Os(1) is bonded to six equivalent O(1) atoms to form corner-sharing OsO6 octahedra. The corner-sharing octahedral tilt angles are 25°. O(1) is bonded in a 5-coordinate geometry to three equivalent Na(1) and two equivalent Os(1) atoms. is represented by the CIF card [CIF]
