The possibility that chelate compounds can be synthesized capable of attaching themselves to 6-covalent metallic atoms in such a way that each single chelate molecule occupies all six octahedrally disposed positions about one metal atom has been in the minds of many chemists for some considerable time, especially since the splendid review of the chelate compounds by Harvey Diehl.'The present paper records what are thought to be the first ...
