The Indigo® 68821W point molecular model set can build boric acid, B(OH)3, to show a planar propeller which is an example of the C3h point group. Other examples of C3h point group molecular geometry include trimethylborane, trimethyl aluminum and carbonic acid.
Use our 3D Molecular Model Builder to show you the chemical structure of the C3h point group molecules listed above. Our organic chemistry model sets can also build point group structures as well. Set the model builder to Orbit (basic) style if have our 68845NV Foundation (basic) chemistry model set, or Orbit (flexible) if you either have our 68827W chemistry advanced organic chemistry molecular model set or the 68847W class organic-inorganic molecular model set.

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.
