Abstract

The bulkiness and multidenticity of the ligands stabilize the unusual trigonal-monopyramidal coordination geometry of the title complexes, which were prepared by “reductive” (Ti, V), “direct” (Cr, Fe), and “oxidative” (Mn) routes. The V complex was characterized by X-ray crystallography (structure shown here).
