Eu2PtZnO6 crystallizes in the monoclinic P2_1/c space group. Eu(1) is bonded in a 8-coordinate geometry to two equivalent O(1), three equivalent O(2), and three equivalent O(3) atoms. Pt(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form PtO6 octahedra that share corners with six equivalent Zn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 32-35°. Zn(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form ZnO6 octahedra that share corners with six equivalent Pt(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 32-35°. There are three inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Eu(1), one Pt(1), and one Zn(1) atom to form distorted corner-sharing OEu2ZnPt tetrahedra. In the second O site, O(2) is bonded in a 5-coordinate geometry to three equivalent Eu(1), one Pt(1), and one Zn(1) atom. In the third O site, O(3) is bonded in a 5-coordinate geometry to three equivalent Eu(1), one Pt(1), and one Zn(1) atom.
