Physical Properties
Dark-red octahedral crystals; volatile and unstable; density 3.83g/cm3; melts at 61.3°C; vaporizes at 69.14°C; reacts violently with water.
Uses
Platinum hexafluoride does not have many commercial applications. It is used as a strong oxidizing agent and can oxidize oxygen from the air. It is used in research. Platinum hexafluoride forms compounds with molecular oxygen and xenon, [O2+][PtF6 –] and XePtF6 , respectively.
Reaction
The hexafluoride is a very powerful oxidizing agent reacting violently with most oxidizable substances. Reaction with liquid water is violent forming HF, oxygen, lower fluorides of platinum, and other products. In vapor phase hydrolysis occurs more smoothly.
The hexafluoride decomposes on heating; also decomposed by UV radiation to lower fluorides; and reacts with the inert gas xenon, forming a solid product, Xe(PtF6). It reacts with molecular oxygen to produce O2+PtF6 – The compound attacks glass at ordinary temperatures.
Hazard
Platinum hexafluoride is dangerously corrosive. Inhalation of its vapors or skin contact causes serious injury. Also, it can react explosively with a number of substances.
Chemical Properties
dark brick red, rhomb solid; strong oxidizing agent; there are also PtF4, 13455-15-7, and PtF5, 13782-84-8 [KIR82]
Check Digit Verification of cas no
The CAS Registry Mumber 13693-05-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,6,9 and 3 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 13693-05:
(7*1)+(6*3)+(5*6)+(4*9)+(3*3)+(2*0)+(1*5)=105
105 % 10 = 5
So 13693-05-5 is a valid CAS Registry Number.

Solid state molecular structures of transition metal hexafluorides
Drews, Thomas,Supel, Joanna,Hagenbach, Adelheid,Seppelt, Konrad
, p. 3782 - 3788 (2006)
Single-crystal structure determinations of all nine transition metal hexafluorides (Mo, Tc, Ru, Rh, W, Re, Os, Ir, and Pt) at -140°C are presented. All compounds crystallize alike and have the same molecular structure. The bond length sequence rW-F ? rRe-F ? rOs-F Ir-F Pt-F is confirmed and paralleled by the sequence rMo-F ? rTc-F ? rRu-F Rh-F. Within the limits of precision, no systematic deviation from octahedral symmetry can be established. DFT and ab initio calculations predict octahedral structures for MoF6 and RhF6 and tetragonally distorted structures for ReF6 and RuF6. The energy barrier toward octahedral structures is only 2.5 kJ mol-1 in the two latter cases. Calculated electron affinities are in the sequence MoF6 6 6 6 with a value of 6.98 eV for the latter. O2 +RhF6- crystallized in an undisordered manner in P1, isostructural to the low-temperature form of O2 +AuF6-. RhF6- has a D4h, compressed octahedral structure, while AuF6 - is essentially octahedral. The absorption spectrum of TcF 6 and the 19F and 195NMR spectra of PtF 6 are presented.
