Five-coordinate rhenium or technetium is found in the trigonal-bipyramidal complexes of type 2. Neutral MIII complexes with this geometry were prepared from the permetalates MO or from the octahedral MIII species with the tetradentate, tripodal ligand 1. The monodentate ligand R in the complexes 2 can be readily substituted.
