Na4PtO4 is Cubic alpha N2-like structured and crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of two Na4PtO4 clusters. There are four inequivalent Na sites. In the first Na site, Na(1) is bonded in a 3-coordinate geometry to one Na(4), one O(2), and one O(3) atom. The Na(1)-Na(4) bond length is 0.15 Å. The Na(1)-O(2) bond length is 0.44 Å. The Na(1)-O(3) bond length is 0.22 Å. In the second Na site, Na(2) is bonded in a single-bond geometry to one Na(3) and one O(1) atom. The Na(2)-Na(3) bond length is 1.05 Å. The Na(2)-O(1) bond length is 1.07 Å. In the third Na site, Na(3) is bonded in a 3-coordinate geometry to one Na(2), one O(1), and one O(4) atom. The Na(3)-O(1) bond length is 1.41 Å. The Na(3)-O(4) bond length is 1.90 Å. In the fourth Na site, Na(4) is bonded in a distorted single-bond geometry to one Na(1) atom. Pt(1) is bonded in a distorted bent 120 degrees geometry to one O(1), one O(3), and one O(4) atom. The Pt(1)-O(1) bond length is 1.21 Å. The Pt(1)-O(3) bond length is 1.19 Å. The Pt(1)-O(4) bond length is 1.50 Å. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one Na(2), one Na(3), one Pt(1), and one O(4) atom. The O(1)-O(4) bond length is 1.71 Å. In the second O site, O(2) is bonded in a single-bond geometry to one Na(1) and one O(4) atom. The O(2)-O(4) bond length is 0.90 Å. In the third O site, O(3) is bonded in a single-bond geometry to one Na(1), one Pt(1), and one O(4) atom. The O(3)-O(4) bond length is 1.01 Å. In the fourth O site, O(4) is bonded in a 5-coordinate geometry to one Na(3), one Pt(1), one O(1), one O(2), and one O(3) atom.
