polytopal rearrangement

https://doi.org/10.1351/goldbook.P04755
Stereoisomerization interconverting different or equivalent spatial arrangements of @L03518@ about a @C00930@ or of a @C00769@ of atoms, where the ligand or @C00769@ defines the vertices of a polyhedron. For example @P04956@ of @A00274@, @P04934@ of PF5, rearrangements of polyhedral @B00709@.
