"sublimes without melting" is redundant. It should just say "sublimes".
[edit] Contradictions
The text says "polymeric structure" but the image shows a single covalent molecule. The melting or sublimation points also need to be straightened out. —Keenan Pepper 15:52, 13 July 2006 (UTC)
I have never heard of AlF3 being polymeric but i don't see why not (except the nonpolar part...) --- How is this contradictary though —The preceding unsigned comment was added by Frozenport (talk • contribs) .
- How is it contradictory? The text says it's polymeric, but the picture doesn't show a polymer. I don't know how else to explain it... —Keenan Pepper 04:57, 14 July 2006 (UTC)

- I suggest you contact the author of the pic, which looks like it was done in Paintbrush (sorry)... 68.39.174.238 09:22, 15 July 2006 (UTC)
The solid is polymeric, but the picture is depicting the four-coordinate gas-phase monomeric form. Perhaps it needs a label/description? Shred-69 (talk) 04:28, 12 February 2008 (UTC)
[edit] Fluoride / Trifluoride
The NIST chemistry webbook calls AlF3 aluminum trifluoride (it has gas phase data which are obviously not from a polymeric state) and calls Al2F6 aluminum fluoride (it has got gas phase data about that substance, too) . Icek 22:08, 12 May 2007 (UTC)
As +3 is the usual oxidation state of aluminium/aluminum, using the term "fluoride" would be acceptable in all but the most formal terms or publications. As this is an encyclopedia, and hence formal, the title should read "Aluminum (III) fluoride" as per the equivalent gallium page, or "Aluminum trifluoride". I'm in the process of building the gallium fluoride page at the moment. Shred-69 (talk) 06:39, 11 February 2008 (UTC)
- Articles are not given the most formal name possible! The general rule is that articles should adopt the most common name for the compound.
