The structure described by Sr2Pr2PtO6 crystallizes in the trigonal R-3 space group. Sr(1) is bonded to six equivalent O(1) atoms to form distorted SrO6 octahedra that share corners with three equivalent Pt(1)O6 octahedra, corners with nine equivalent Pr(1)O6 octahedra, edges with three equivalent Sr(1)O6 octahedra,  a faceface with one Pr(1)O6 octahedra, and  a faceface with one Pt(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 37-60°. Pr(1) is bonded to six equivalent O(1) atoms to form distorted PrO6 octahedra that share corners with nine equivalent Sr(1)O6 octahedra, edges with three equivalent Pr(1)O6 octahedra, edges with three equivalent Pt(1)O6 octahedra, and  a faceface with one Sr(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 37-60°. Pt(1) is bonded to six equivalent O(1) atoms to form PtO6 octahedra that share corners with six equivalent Sr(1)O6 octahedra, edges with six equivalent Pr(1)O6 octahedra, and faces with two equivalent Sr(1)O6 octahedra. The corner-sharing octahedral tilt angles are 40°. O(1) is bonded to two equivalent Sr(1), two equivalent Pr(1), and one Pt(1) atom to form a mixture of distorted corner and edge-sharing OSr2Pr2Pt trigonal bipyramids. is represented by the CIF card [CIF]
