Abstract

NMR spectra of highly saddled Mn(III) porphyrinates such as Mn(OETPP)(CD3OD)2 + have been measured. The extraordinarily upfield shifted meso-13C signals, which reach as much as -492 ppm at 298 K, are ascribed to the dx2-y2-a2u, dxy-a1u, and dπ-3eg interactions, the former two of which occur only when the porphyrin ring is saddled.
