Novel phthalocyanine complexes of zirconium (IV) and hafnium (IV) containing dibenzoylmethane groups as out-of-plane ligands were synthesized and characterized by elemental analyses, GALDI mass spectrometry, IR, 1 H NMR, UV–vis and fluorescence spectroscopy. The structures of the complexes were determined by single-crystal X-Ray diffraction. The synthesized compounds are isomorphous, with...
A range of zirconium(IV) and hafnium(IV) phthalocyanines with various carboxylic acids as out-planed ligands has been synthesized by a direct interaction between di(chloro)zirconium(IV)- or hafnium(IV)-phthalocyanines and carboxylic acids. Coordination of two acid fragments is suggested to occur in a cis-geometry about the central atom of the macrocycle as evidenced on the basis of 1 H NMR,...
