The material structure described by K3(PtO2)2 crystallizes in the orthorhombic Cmcm space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 4-coordinate geometry to four equivalent O(1) atoms. In the second K site, K(2) is bonded in a 6-coordinate geometry to six equivalent O(1) atoms. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a distorted square co-planar geometry to four equivalent O(1) atoms. In the second Pt site, Pt(2) is bonded in a distorted square co-planar geometry to four equivalent O(1) atoms. O(1) is bonded to one K(1), three equivalent K(2), one Pt(1), and one Pt(2) atom to form a mixture of distorted face, corner, and edge-sharing OK4Pt2 octahedra. The corner-sharing octahedral tilt angles range from 0-70°. is represented by the CIF file [CIF]
