The crystal structure described by Na8PtO6 crystallizes in the tetragonal P4 space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded in a distorted rectangular see-saw-like geometry to one O(1) and three equivalent O(3) atoms. In the second Na site, Na(2) is bonded in a 4-coordinate geometry to one O(1), one O(2), and two equivalent O(3) atoms. Pt(1) is bonded to two equivalent O(2) and four equivalent O(3) atoms to form corner-sharing PtO6 octahedra. The corner-sharing octahedra are not tilted. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 8-coordinate geometry to four equivalent Na(1) and four equivalent Na(2) atoms. In the second O site, O(2) is bonded to four equivalent Na(2) and two equivalent Pt(1) atoms to form ONa4Pt2 octahedra that share corners with two equivalent O(2)Na4Pt2 octahedra and edges with eight equivalent O(3)Na5Pt octahedra. The corner-sharing octahedra are not tilted. In the third O site, O(3) is bonded to two equivalent Na(2), three equivalent Na(1), and one Pt(1) atom to form ONa5Pt octahedra that share corners with five equivalent O(3)Na5Pt octahedra, edges with two equivalent O(2)Na4Pt2 octahedra, and edges with three equivalent O(3)Na5Pt octahedra. The corner-sharing octahedral tilt angles range from 0-24°. is represented by the CIF card [CIF]
