Na3(Pt3O4)4 crystallizes in the cubic Fm-3 space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded in a body-centered cubic geometry to eight equivalent O(1) atoms. In the second Na site, Na(2) is bonded in a body-centered cubic geometry to four equivalent O(1) and four equivalent O(2) atoms. Pt(1) is bonded in a square co-planar geometry to two equivalent O(1) and two equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded to one Na(1), one Na(2), and three equivalent Pt(1) atoms to form ONa2Pt3 trigonal bipyramids that share corners with seven equivalent O(1)Na2Pt3 trigonal bipyramids, corners with four equivalent O(2)NaPt3 trigonal pyramids, edges with three equivalent O(1)Na2Pt3 trigonal bipyramids, and edges with three equivalent O(2)NaPt3 trigonal pyramids. In the second O site, O(2) is bonded to one Na(2) and three equivalent Pt(1) atoms to form ONaPt3 trigonal pyramids that share corners with four equivalent O(1)Na2Pt3 trigonal bipyramids, corners with six equivalent O(2)NaPt3 trigonal pyramids, and edges with three equivalent O(1)Na2Pt3 trigonal bipyramids.
