The Unit 69177 Teacher's molecular model set can build B(OH)3 to show a planar propeller which is an example of the C3 point group.
The atoms in this Large Point Group Classroom Model set can assume any geometry. Go to the bottom of page Unit Molecular Models for an overview or click on the Instructions/Safety tab to see videos on how to construct any molecular geometry.
