The material structure described by PtO3 is Upper Bainite-like structured and crystallizes in the orthorhombic Pnma space group. Pt(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form corner-sharing PtO6 octahedra. The corner-sharing octahedral tilt angles range from 49-54°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to two equivalent Pt(1) atoms. In the second O site, O(2) is bonded in a bent 120 degrees geometry to two equivalent Pt(1) atoms. is represented by the CIF file [CIF]
