Observations of the photoredox reactivity of antimony(III) porphyrin complexes are reported. Upon irradiation\udwith visible light under ambient conditions, a photooxidation to the corresponding dihydroxoantimony(V) porphyrins\udoccurs. At the same time a two-electron or four-electron reduction of molecular oxygen takes place, depending on\udthe experimental conditions. In the absence of suitable electron acceptors, a photoinduced disproportionation reaction occurs. The photolysis of antimony(III) porphyrins shows a pronounced wavelength dependence. The reactive\udexcited state is concluded to be of the metal-centered sp type. An extended model for the electronic structure of\udp-type hyper metalloporphyrins is suggested
