Binuclear Fluoro-Bridged Zinc and Cadmium Complexes of a Schiff Base Expanded Porphyrin: Fluoride Abstraction from the Tetrafluoroborate Anion
摘要:
Reactions of the Schiff base oligopyrrolic octaazamacrocycle 1 with BF4- salts of divalent zinc and cadmium result in fluoride anion abstraction and the formation of difluoride-bridged metal complexes. X-ray diffraction analyses provide support for the notion that hydrogen-bonding interactions, involving the N-H groups of the macrocycle and the coordinated fluoride ions, play an important role in stabilizing these new complexes.

New bimetallic mu-oxo diferric complexes of several previously reported calix[4]pyrrole Schiff base macrocycles are described. The synthesis of a new member of this class of macrocycles is also reported; it was prepared via an acid-catalyzed condensation between 1,9-bisformyl-5,5-dipropyldipyrromethane and o-phenylenediamine. Reactions of the free base macrocycles or their bis-HCl salts with Fe(II)
