Symmetry
[edit]It says: "In the solid-state, the molecule has D5h symmetry, wherein the two rings are eclipsed." Looking at the picture, it's D5d though! Chris (talk) 06:17, 26 July 2008 (UTC)
- Acta Cryst. (1980). B36, 2255-2260 notes that the energy barrier between eclipsed and staggered conformations in nickelocene must be very low, that the gas-phase structure was (at the time) unconfirmed and that in the monoclinic crystal structure, the staggered conformation is observed.
The source quoted states the structure as being D5d (staggered) as well — Preceding unsigned comment added by Sakashar (talk • contribs) 11:39, 28 December 2018 (UTC)
