Materials Data on Eu2ZnPtO6 by Materials Project
Eu2PtZnO6 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Eu3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Eu–O bond distances ranging from 2.36–2.80 Å. Pt4+ is bonded to six O2- atoms to form PtO6 octahedra that share corners with six equivalent ZnO6 octahedra. The corner-sharing octahedra tilt angles range from 32–35°. There are two shorter (2.03 Å) and four longer (2.04 Å) Pt–O bond lengths. Zn2+ is bonded to six O2- atoms to form ZnO6 octahedra that share corners with six equivalent PtO6 octahedra. The corner-sharing octahedra tilt angles range from 32–35°. There are a spread of Zn–O bond distances ranging from 2.07–2.15 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded to two equivalent Eu3+, one Pt4+, and one Zn2+ atom to form distorted corner-sharing OEu2ZnPt tetrahedra. In the second O2- site, O2- is bonded in a 5-coordinate geometry to three equivalent Eu3+, one Pt4+, and one Zn2+ atom. In the third O2- site, O2- is bonded in a 5-coordinate geometry to three equivalent Eu3+, one Pt4+, and one Zn2+ atom.
