Symmetry

It says: "In the solid-state, the molecule has D_5h symmetry, wherein the two rings are eclipsed." Looking at the picture, it's D_5d 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 D_5d (staggered) as well — Preceding unsigned comment added by Sakashar (talk • contribs) 11:39, 28 December 2018 (UTC)
