As a prototypical metallocene with a sandwich structure, ferrocene exhibits only a small energy barrier separating the staggered (D5d symmetry) and eclipsed (D5h symmetry) rotational orientations of the parallel cyclopentadienyl rings [8].
Is ferrocene staggered or eclipsed?
Why is ferrocene staggered?
Staggered Ferrocene contains a main C5 axis with 5 perpendicular C2 axes. There is a S10 improper rotation axis. It also contains 5 σd planes. Hence it belongs to the D5d point group.
Why is ferrocene eclipsed?
It therefore discovers that the major difference between the ferrocene conformers is due to the quantum mechanical Pauli repulsive energy and orbital attractive energy, leading to the eclipsed ferrocene the energy preferred structure.
Is eclipsed or staggered ferrocene more stable?
The staggered conformation is believed to be most stable in the condensed phase due to crystal packing.
What kind of compound is ferrocene?
organometallic compound Ferrocene is an organometallic compound of the general class metallocene with the molecular formula Fe(η5-C5H5)2. In this molecule, iron is sandwiched between two cyclopentadienyl rings in staggered conformation, as shown in Figure 6.
What are the symmetry point groups for the eclipsed and staggered forms of ferrocene?
As a prototypical metallocene with a sandwich structure, ferrocene exhibits only a small energy barrier separating the staggered (D5d symmetry) and eclipsed (D5h symmetry) rotational orientations of the parallel cyclopentadienyl rings [8].

What is the point group of staggered ethane?
So far we can say staggered ethane has three operations: E, C3, and C3 2 Page 3 Symmetry in Molecules: Staggered Ethane So we add three more operations: C2, C2′, and C2″ Page 4 Now we've added three reflections: σd, σd′, and σd″ Note that there is no σh for staggered ethane!
