The structure described by Na2PtO2 is Ilmenite-like structured and crystallizes in the orthorhombic Immm space group. Na(1) is bonded to four equivalent O(1) atoms to form a mixture of distorted edge and corner-sharing NaO4 trigonal pyramids. Pt(1) is bonded in a square co-planar geometry to four equivalent O(1) atoms. O(1) is bonded to four equivalent Na(1) and two equivalent Pt(1) atoms to form a mixture of edge and corner-sharing ONa4Pt2 octahedra. The corner-sharing octahedral tilt angles range from 0-17°. is represented by the Crystallographic Information File (CIF) [CIF]
