Far‐reaching analogies between μ‐oxodiiron( III ) complexes of porphycenes and porphyrins with regard to physical, chemical, and structural properties are revealed by investigations of the new metallopor‐phycenes 1 (R n Pr, t Bu). These are obtained by using standard methods for porphyrin chemistry. The Fe‐O‐Fe angle in 1 (R n Pr) differs widely (145°) from those of the metalloporphyrins (161–180°) and that of 1 (R t Bu; 179°) as a result of reduced steric interactions.
