The crystal structure described by Sm2PtZnO6 crystallizes in the monoclinic P2_1/c space group. Sm(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 35-38°. 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 35-38°. There are three inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Sm(1), one Pt(1), and one Zn(1) atom to form distorted corner-sharing OSm2ZnPt trigonal pyramids. In the second O site, O(2) is bonded in a 5-coordinate geometry to three equivalent Sm(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 Sm(1), one Pt(1), and one Zn(1) atom. is represented by the CIF card [CIF]
