Bindungslänge von O2– in Å?
Ich finde leider nirgends die Bindungslänge von O2–, kann mir da jemand behilflich sein + Quelle angeben? Für O2+, O2, O2- habe ich bisweilen r/Å: 1.1164, 1.2075, 1.3500 auf cccbdb.nist.gov gefunden, doch O2– ist dort leider nicht gelistet und auf anderen Datenbanken habe ich es auf den ersten Blick leider auch nicht gefunden.
1,20741 Å; Holleman-Wiberg.
Are you referring to the following table? https://ibb.co/rM71bNH where did you get your value from the book? The current Holleman is 1.49 Å for O2–
No, the 91st-100. Volume, 1985; 1.1.3 Physical properties; Page 451. 1.48 Å are given there for a single bond.
Yeah, you can’t write any chemical formulas right here at GF. But that’s exactly the value.
I also asked about the peroxide anion “O2–“
By the way: In the table linked by you, it is also in my Holleman, on page 455, the right value for triplet oxygen of 1.21 Å (rounded to 2 decimal places) is in it. The 1.49 Å applies to the peroxide anion.
Hmm, that’s a big difference. Do you think the current (1.48 Å) is more accurate or should I rather take yours?
