The Crystal Structure of NaPt3O4

Abstract

The structure of a microcrystalline platinum compound is derived from x‐ray data. Space group O_h³—Pm3n, a₀=5.69A, with 6 Pt at ±(¼ 0 ½, ↺), 8 O at ±(¼ ¼ ¼, ¼ ¾ ¾, ↺), and 2 Na at (000, ½ ½ ½), corresponding to the formula NaPt₃O₄. The coordinations are as follows: platinum 4 O and 2 Pt, oxygen: 3 O and 2 Na, sodium: 8 O. The substance is an ionic conductor.
