Materials Data on Zn(PtO2)3 by Materials Project
Zn(PtO2)3 crystallizes in the orthorhombic Cmmm space group. The structure is three-dimensional. there are two inequivalent Pt+3.33+ sites. In the first Pt+3.33+ site, Pt+3.33+ is bonded to six O2- atoms to form a mixture of edge and corner-sharing PtO6 octahedra. The corner-sharing octahedral tilt angles are 59°. There are four shorter (2.05 Å) and two longer (2.07 Å) Pt–O bond lengths. In the second Pt+3.33+ site, Pt+3.33+ is bonded in a square co-planar geometry to four equivalent O2- atoms. All Pt–O bond lengths are 1.99 Å. Zn2+ is bonded in a distorted body-centered cubic geometry to eight O2- atoms. There are four shorter (2.20 Å) and four longer (2.45 Å) Zn–O bond lengths. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to three Pt+3.33+ and one Zn2+ atom to form a mixture of distorted edge and corner-sharing OZnPt3 tetrahedra. In the second O2- site, O2- is bonded to two equivalent Pt+3.33+ and two equivalent Zn2+ atoms to form a mixture of edge and corner-sharing OZn2Pt2 tetrahedra.
