When HF is bubbled through a solution of (L=porphyrinate), porphyrinatoniobium oxide fluoride complexes are formed.The structures of some of these complexes have been studied from analytical and spectroscopic data.The title compound has been determined by X-ray diffraction methods.Crystals are monoclinic space group P21/c with a=15.007(3), b=22.257(4), c=10.058(2) Angstroem, β=77.85(2) deg, and Z=4.

Zinc amalgam or electrochemical reduction of porphyrinatoniobium(V) oxide acetates leads to porphyrinatoniobium(IV) oxides, which are characterized by their e.s.r., i.r., and u.v.-vis. spectra.
