Sr3NiPtO6 crystallizes in the trigonal R-3c space group. Sr(1) is bonded in a 8-coordinate geometry to eight equivalent O(1) atoms. Pt(1) is bonded to six equivalent O(1) atoms to form PtO6 octahedra that share faces with two equivalent Ni(1)O6 pentagonal pyramids. Ni(1) is bonded to six equivalent O(1) atoms to form distorted NiO6 pentagonal pyramids that share faces with two equivalent Pt(1)O6 octahedra. O(1) is bonded to four equivalent Sr(1), one Pt(1), and one Ni(1) atom to form a mixture of distorted edge, face, and corner-sharing OSr4NiPt octahedra. The corner-sharing octahedral tilt angles range from 0-67°.
