B(OH)3 B(OH)3
View down -6 axis View perpendicular to -6 axis

This molecule has a sixfold rotary-inversion axis (which is less easy to spot than the threefold rotation axis), and no other symmetry axes. The presence of the -6 axis automatically implies the presence of a colinear 3 axis perpendicular to a mirror plane.

The point-group symmetry for this molecule is given the crystallographic symbol -6.
