[Re₂Cl₈]^2- Worked Example

It may help to follow this tutorial whilst looking at The Flow Diagram to follow the process of arriving at the point group.

Help

A C₅ axis is a rotation around a point which can be completed 5 times before returning to the original position of the molecule.

E.g. a rotation of 72° (360°/5 = 72) will give the same configuration of the molecule (as can be shown by the C5 axis in eclipsed ferrocene shown below).

Does [Re₂Cl₈]^2- have two of more C₅ axes of rotation?
YES
NO
