Hafnium(IV) chloride edit

Hey Mogiemilly - I see that you have started to work on HFCl4. Here are some suggestions on what might prove to be even more challenging than your "famous" AgF2 work. The structure needs to be described. I suspect that it is very similar structurally to ZrCl4, which is polymeric, i.e. non-molecular. You could contrast that structure (and properties) with TiCl4. One challenge will be to identify anything that HfCl4 does differently from ZrCl4! Possibly the greatest different will be that HfCl4 is more difficult to reduce (to HfCl3) than is Zr(IV). Maybe you can find a redox potential. HfCl4 almost certainly makes (C5H5)2HfCl2, again analogous to Zr, which has probably been examined as a catalyst for polyethylene. --Smokefoot 21:16, 18 February 2006 (UTC)Reply

I've left a note at Talk:Hafnium(IV) chloride about the preparation of this compound. You should mention its complex with tetrahydrofuran, which is an important starting material in hafnium chemistry: as a monomeric complex it is much more soluble that the uncomplexed chloride, and so easier to get to react. You should also read the specifications of commercial HfCl4 very carefully, and see if there is anything which should be mentioned in this article :) Physchim62 (talk) 05:03, 28 February 2006 (UTC)Reply

Imidazole edit

Hi Ariel, good work on the imidazole article. It has long been listed in the Chemicals wikiproject as a mere Stub article, and now I just re-assessed it as B-Class. Thanks! Perhaps you'd like to join? Wim van Dorst (Talk) 21:24, 8 April 2006 (UTC).Reply

Thanks a lot, I really enjoy writing for wiki. I am actually a college student in a chemistry class, and selecting a stub article was an assignment. My professor is User:Smokefoot, and this is the third and final article we were assigned. I probably won't have the time or resources to help much more anytime soon, but thanks for the invite!

Proposed deletion of File:Onebondmethod.gif edit

 

The file File:Onebondmethod.gif has been proposed for deletion because of the following concern:

Unused, better vector version on commons

While all constructive contributions to Wikipedia are appreciated, pages may be deleted for any of several reasons.

You may prevent the proposed deletion by removing the {{proposed deletion/dated files}} notice, but please explain why in your edit summary or on the file's talk page.
