The synthesis and characterization of nine indium(III) porphyrin complexes with three types of ?-bonded tetrazolato axial ligands are reported.The investigated compounds In(por)(N4CR) where R=CMe3, CH=CH2 or CH=CHCN and por = the dianion of 2,3,7,8,12,13,17,18-octaethylporphyrin (oep), 5,10,15,20-tetraphenylporphyrin (tpp) or 5,10,15,20-tetra-p-trifluoromethylphenylporphyrin (tfpp) were characterized by UV/VIS, IR and (1)H NMR spectroscopy as well as by electrochemistry.The N4CR ligand of a given M(por)(N4CR) complex can have the R group attached to either the 4 or 5 position of the tetrazolato ring and this is discussed in the present study with respect to the steric and electronic effects of the axial and equatorial ligands.
