Ba4PtO6 crystallizes in the trigonal R-3c space group. There are two inequivalent Ba sites. In the first Ba site, Ba(1) is bonded in a 6-coordinate geometry to six equivalent O(1) atoms. In the second Ba site, Ba(2) is bonded in a 8-coordinate geometry to eight equivalent O(1) atoms. Pt(1) is bonded in an octahedral geometry to six equivalent O(1) atoms. O(1) is bonded to one Ba(1), four equivalent Ba(2), and one Pt(1) atom to form a mixture of edge, face, and corner-sharing OBa5Pt octahedra. The corner-sharing octahedral tilt angles range from 0-60°.
Ba4PtO6 crystallizes in the trigonal R-3c space group. There are two inequivalent Ba sites. In the first Ba site, Ba(1) is bonded in a 6-coordinate geometry to six equivalent O(1) atoms. All Ba(1)-O(1) bond lengths are 2.63 Å. In the second Ba site, Ba(2) is bonded in a 8-coordinate geometry to eight equivalent O(1) atoms. There are a spread of Ba(2)-O(1) bond distances ranging from 2.75-2.90 Å. Pt(1) is bonded in an octahedral geometry to six equivalent O(1) atoms. All Pt(1)-O(1) bond lengths are 2.10 Å. O(1) is bonded to one Ba(1), four equivalent Ba(2), and one Pt(1) atom to form a mixture of edge, face, and corner-sharing OBa5Pt octahedra. The corner-sharing octahedral tilt angles range from 0-60°.
