    Description: We report on the single crystal structure of Na 2 PtF 6 , which was synthesized from (NH 4 ) 2 PtCl 6 and NaCl in a flow of 10 % F 2 in argon. The light yellow compound crystallizes in the Na 2 SiF 6 structure type with the trigonal space group P 321 and the lattice parameters a = 9.2981(2), c = 5.1147(1) Å, and V = 382.95(1) Å 3 at 123 K with Z = 3. Na 2 PtF 6 reacts with liquid ammonia yielding bis triamminesodium hexafluoridoplatinate(IV) [Na(NH 3 ) 3 ] 2 [PtF 6 ]. It crystallizes in the monoclinic space group C 2/ c with a = 14.0508(4), b = 8.4894(1), c = 12.8820(4) Å, β = 120.495(4)°, and V = 1324.05(6) Å 3 at 123 K with Z = 4. In contrast to the aqueous system, the solvolysis in NH 3 does not lead to the cleavage of the Pt–F bonds, at least not at the temperatures employed in this study.
