The Indigo® Instruments 68821W Point Group molecular model set can build an eclipsed ferrocene o show an example of a D5h point group. This eclipsed Ferrocene shows the C5 main rotation axis and its 5 perpendicular C2 axes.
The D5h cannot be built with any of the following: Orbit 68845NV organic chemistry model kit, the advanced Orbit 68827W Chemistry Structures Molecular Model Set & the 68847W Class Organic-Inorganic Molecular Model set.
Note that the image show ferrocene in the eclipsed configuration; the point group set only includes enough parts to build one ferrocene model.

This model set has the flexibility needed to teach symmetry point groups effectively, as well as modeling metal coordination complexes. Some atoms have holes perpendicular to their main bonds, allowing for modeling H-bonds or electrostatic interactions. Construction-wise, atoms pieces are smaller relative to the bond pieces, emphasizing the relative space taken up by orbitals compared to nuclei. However, this can also make it difficult to change molecular structure quickly. Indigo Instruments customer service was also very helpful in processing my order quickly and completing forms required by my institution for requisition.
Thanks for the feedback. It is an unusual set & the only one we know of that can build ferrocene.
