Flammability and Explosibility
Notclassified
Safety Profile
Poison by inhalation and ingestion. Human pulmonary system effects by inhalation. See also PLATINUM COMPOUNDS. An explosively unstable compound. Incompatible with KOH (boiling with alkali yields a product which, after drying, will explode @ 205' or if mixed with combustibles). When heated to decomposition it emits very toxic fumes of Cl-, NOx, and NH3.
Potential Exposure
It is used in photography, platinum
plating and in the manufacture of platinum sponge.

Name Required.
Incompatibilities
This material is unstable and potentially
explosive. Incompatible with strong oxidizers (chlorates,
nitrates, peroxides, permanganates, perchlorates,
chlorine, bromine, fluorine, etc.); contact may cause fires
or explosions. Keep away from alkaline materials, strong
bases, strong acids, oxoacids, epoxides.
Waste Disposal

the metal, recovery is the economically indicated disposal
method.
Check Digit Verification of cas no
The CAS Registry Mumber 16919-58-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,9,1 and 9 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 16919-58:
(7*1)+(6*6)+(5*9)+(4*1)+(3*9)+(2*5)+(1*8)=137
137 % 10 = 7
So 16919-58-7 is a valid CAS Registry Number.

The first fluoride A2[PtF6] of the K2PtCl6 type: β-Cs2[PtF6]
Bork,Hoppe
, p. 417 - 424 (1996)
For the first time, yellow cubic single crystals of Cs2[PtF6] have been obtained by solid state reaction, heating (Pt-tube, 35 d, 800°C) the fluorination product of an intimate mixture of (NH4)2PtCl6 and 2 CsCl (diluted F2, F2:N2 = 1:5, 10 d, 400°C). The new form is isostructural with K2PtCl6: Fm3m; a = 905.5(2) pm; Z = 4 (Guinier-de Wolff data, CuKα1); R = 2.32% (SHELX-76); 1398 I0(hk1), Image-Plate diffractometer data (Stoe IPDS). It is compared with already known α-Cs2[PtF6] (K2GeF6-type, P3m1). The Madelung-Part of Lattice Energy, MAPLE, Effective Coordination Numbers, ECoN, and Mean Fictive Ionic Radii, MEFIR, are calculated and discussed in comparison with the data of further Hexafluoroplatinates(IV). A complete analysis of MAPLE was carried out for the title compound as well as for the α- and a hypothetical α′-form. Johann Ambrosius Barth 1996.
