A
polytopal rearrangement in which the change in bond directions to a three-coordinate
central atom having a pyramidal arrangement of bonds (tripodal arrangement) causes the
central atom (
apex of the pyramid) to appear to move to an equivalent position on the other side of
the base of the pyramid. If the three
ligands to the
central atom are different pyramidal
inversion interconverts
enantiomers.
