The crystal structure described by Zn(PtO2)3 crystallizes in the orthorhombic Cmmm space group. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form a mixture of edge and corner-sharing PtO6 octahedra. The corner-sharing octahedral tilt angles are 59°. In the second Pt site, Pt(2) is bonded in a square co-planar geometry to four equivalent O(1) atoms. Zn(1) is bonded in a distorted body-centered cubic geometry to four equivalent O(1) and four equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded to one Pt(2), two equivalent Pt(1), and one Zn(1) atom to form distorted OZnPt3 tetrahedra that share corners with four equivalent O(2)Zn2Pt2 tetrahedra, corners with eight equivalent O(1)ZnPt3 tetrahedra, edges with two equivalent O(2)Zn2Pt2 tetrahedra, and edges with two equivalent O(1)ZnPt3 tetrahedra. In the second O site, O(2) is bonded to two equivalent Pt(1) and two equivalent Zn(1) atoms to form OZn2Pt2 tetrahedra that share corners with six equivalent O(2)Zn2Pt2 tetrahedra, corners with eight equivalent O(1)ZnPt3 tetrahedra,  an edgeedge with one O(2)Zn2Pt2 tetrahedra, and edges with four equivalent O(1)ZnPt3 tetrahedra. is represented by the CIF file [CIF]
