In the eleventh O site, O(11) is bonded to one Na(1), one Na(5), one Na(6), one Na(7), one Pt(2), and one Pt(4) atom to form a mixture of corner and edge-sharing ONa4Pt2 octahedra. The corner-sharing octahedral tilt angles range from 6-9°. In the twelfth O site, O(12) is bonded to one Na(2), one Na(3), one Na(4), one Na(8), one Pt(1), and one Pt(3) atom to form a mixture of distorted corner and edge-sharing ONa4Pt2 octahedra. The corner-sharing octahedral tilt angles range from 5-10°. is represented by the Crystallographic Information File (CIF) [CIF]
