## Abstract The structure of (TMA)~2~[TiF~6~] was determined to be rhombohedral (pseudo-cubic) at room temperature and has been refined to __wR__ = 7.6%. It is isostructural with (TMA)~2~[OsF~6~]. Crystals grown from aqueous solution have pseudo-octahedron and pseudo-cube faces and exhibit twinning

## Abstract (TMA)~2~[PtF~6~] is found to be tetragonal at room temperature (space group __I__4/__m__, __a__ = 8.073(9) Å, __c__ = 11.401(2) Å). The structure is related to the K~2~[PtCl~6~] structure type (space group __Fm__[unk]__m__) and is characterized by a ferrorotative tilt of the [PtF~6~] oc
