Shopping on line can be easy, simple and save you lots of money. It can also take a lot of your time, frustrate you, and result in unwanted purchases. Now the same can be said for regular high street shopping, but with the vast opportunity presented by the Internet it will pay you to spend a few minutes reading this and understanding how to better optimize your Xenon Hexafluoroplatinate shopping experience:
1. Compare - without doubt the biggest advantage that the Xenon Hexafluoroplatinate offers shoppers today is the ability to compare thousands of Xenon Hexafluoroplatinate at a time. This is a great thing, but not necessarily all the time! Too much can be daunting at times so take advantage of the great comparison sites and where possible let them do the hard work for you.
2. Research - if it has been said it will be on the internet. Ignorance is no longer a justifiable reason for buying the wrong thing. Take the time to research in detail everything that you could possible want to know about
3. Testimonials - don't know anybody that has bought a Xenon Hexafluoroplatinate? Wrong! If the Xenon Hexafluoroplatinate is good the internet will let you know. Use the Internet as a friend and get testimonials before you buy.
4. Questions - Got a question about Xenon Hexafluoroplatinate then search the Forums, FAQ's, Blogs etc. Don't be afraid to ask .....
5. Reputation - Never heard of the company selling Xenon Hexafluoroplatinate? Don't worry, no reason why you should know every company in the world, but you know someone that does! Use the internet to find out what people are saying about Xenon Hexafluoroplatinate and build up a picture of their reputation for sales, returns, customer service, delivery etc.
6. Returns - still worried that even after all of the above your Xenon Hexafluoroplatinate wont be what you want? Check out the returns policy. There is so much competition now that someone, somewhere is bound to offer the terms that you are comfortable with.
7. Feedback - happy with your Xenon Hexafluoroplatinate then let people know, after all you are depending on others people input in your buying decision, so why not give a little back.
8. Security - check for the yellow padlock on the Xenon Hexafluoroplatinate site before you buy, and the s after http:/ /i.e. https:// = a secure site
9. Contact - got a question about Xenon Hexafluoroplatinate, or want to leave a comment then check out the sites contact page. Reputable companies have them and respond.
10. Payment - ready to pay for your Xenon Hexafluoroplatinate, then use your credit card or PayPal! Be aware of companies that don't accept them, there may be genuine reasons but given the huge amount of choice you have when buying online there is no reason at all not to buy via credit card or PayPal.

Xenon hexafluoroplatinate is the description of the product obtained from the combination of platinum hexafluoride and
xenon in an experiment that proved the chemical reactivity of the noble gases. Neil Bartlett at the University of British Columbia formulated the product as "Xe+−", although subsequent work suggests that Bartlett's product was probably a mixture and did not in fact contain this specific salt.
Preparation
"Xenon hexafluoroplatinate" is prepared from Xe and
platinum hexafluoride (PtF6) as gaseous
solutions in SF6. The reactants were combined at 77kelvin and slowly warmed, presumably to allow for a controlled reaction.
What is "xenon hexafluoroplatinate"?
The structure of "xenon hexafluoroplatinate" is likely not Xe+−. The main problem with this formulation is "Xe+", which would be a
Radical (chemistry) and would
dimerize or abstract an F atom to give XeF+. Thus, Bartlett discovered that
Xenon undergoes chemical reactions, but the nature of his initial mustard yellow product is complex. Further work indicates that Bartlett's product probably contained −, −, .Holleman, A. F.; Wiberg, E. "Inorganic Chemistry" Academic Press: San Diego, 2001. ISBN 0-12-352651-5. The title "compound" is a salt, consisting of an
octahedral anionic fluoride complex of platinum and various xenon cations.The American Chemical Society "molecule of the week" (2006). "Xenon Hexafluoroplatinate"
It has been proposed that the platinum fluoride forms a negatively charged
polymeric network with xenon or xenon fluoride
cations held in its Interstitial defect. A preparation of "XePtF6" in hydrogen fluoride solution results in a solid which has been characterized as a n polymeric network associated with XeF+. This result is evidence for such a polymeric structure of xenon hexafluoroplatinate.
History
In 1962, Neil Bartlett discovered that a mixture of platinum hexafluoride gas and oxygen formed a red solid.Bartlett, N. (1962). Xenon hexafluoroplatinate Xe+−
Proceedings of the Chemical Society of London 218-. The red solid turned out to be
dioxygenyl hexafluoroplatinate, O2+-. Bartlett later surmized that the ionization energies for O2 molecule and Xe were similar. He then asked his colleagues to give him some xenon "so that he could try out some reactions", whereupon he established that xenon indeed reacts with PtF6. Although, as discussed above, the product was probably highly impure, Bartlett's discovery was the first proof that compounds could be prepared from a
noble gas. His discovery illustrates that the discovery of new chemical methods often lead Initially to impure products. Since Bartlett's discovery, many well-defined compounds of xenon have been reported including XeF2, XeF4, and
XeF6.
