Structure of gas-phase N2O5

The picture of the molecular structure correctly indicates the known bond angles in the gas phase compound. The source for this information should be cited: Hedberg, et al., J. Am. Chem. Soc. 1983, 105, 3789-3793. However, the shape of the molecule is incorrect, as is the "Structure" box farther down. Recent theoretical calculations (Theor. Exp. Chem. 2007, 43, 66-70 and references therein) suggest that a non-planar Cs structure, with the NO2 groups rotated 90º relative to the central NON plane, is the lowest energy gas phase structure. The indication in the Structure box that the symmetry is nearly D2h because of an near 180 NON angle is incorrect. —Preceding unsigned comment added by 142.231.66.25 (talk) 17:47, 17 October 2009 (UTC)

NO₂BF₄

• I'm not sure what the name is that goes with the formula NO₂BF₄. Should we not make it more clear in the article? Ruff ^{Bark away!} 03:24, 26 September 2006
• What is the text name of NO₂BF₄? Nitrosyl borofluoride, or nitrosyl fluoroborate, or what? Anthony Appleyard 08:27, 10 October 2006 (UTC)
• The naming is confusing and should be better explained in the article. Nitronium ion = NO₂⁺, nitrosonium ion = NO⁺, also called nitrosyl. NOBF₄ is called nitrosyl fluoroborate or nitrosyl tetrafluoroborate by practitioners.--Smokefoot 16:29, 10 October 2006 (UTC)
• Nitronium/nitryl (tetra)fluoroborate? Anthony Appleyard 17:14, 10 October 2006 (UTC)
• from SigmaAldrich.com who sell the SbF₆^- and four versions of the BF₄^- salts:

"Nitronium hexafluoroantimonate (1) Nitronium tetrafluoroborate (3) Linear Formula: NO2BF4, Formula Weight: 132.81, CAS Number: 13826-86-3 73508 purum, packed in PTFE bottles, ≥95.0% (T) (Fluka) 366153 ≥95% (Aldrich) 175021 85% (Aldrich) Nitronium tetrafluoroborate solution (2)" --Smokefoot 18:13, 10 October 2006 (UTC)

ClNO2 or NO2Cl?

The inconsistent use between the two may mislead readers into thinking they are different compounds, or are bounded differently. Personally, I find ClNO2 to be the more accurate of the two, but as a student, I'd like an in-the-field professional to verify my claim. I realize they are both "accurate" in that the compound is composed of the same proportions of elements, but anyone who's learned organic chemistry knows one cannot simply deduce their chemical structures off reading the numbers of carbons and hydrogens and whatever within the element alone.
