Talk:Sulfur trioxide pyridine complex

"The compound strongly violates the octet rule, as sulfur here has 12 or 14 electrons in its valence shells, depending on whether the S-N bond is viewed as dative or not."

I have two issues with this. First, pyridine.SO3 violates the octet rule. As do H2SO4, H2SO3, SF6, POCl3, ClF3. The octet rule only holds strongly for second row elements, for the rest many exceptions exist. Not sure if it's worth mentioning here.

Second, the sulfur in pyridine.SO3 always has 12 valence electrons, no matter how you view it. At least that part of the sentence should likely be removed.

Safety?
This section is missing entirely. I would expect that it would need caution when handling, since it's used as a source of (very corrosive) SO3. Hellbus (talk) 01:16, 3 May 2022 (UTC)
 * I just dont think that people use pySO3 on scale but as a reagent in fancy syntheses. Hence the article is very brief on apps.  I also suspect that it isnt particular nasty since the strong Lewis acidity of SO3 is quenched.  Our article on SO3 has a blunt statement about dangers.--Smokefoot (talk) 12:42, 3 May 2022 (UTC)
