The great majority of low-spin {FeNO}(7) complexes exhibit FeNO angles of around 140-145 degrees, whereas a small handful are characterized by linear FeNO units. Conspicuously absent are intermediate FeNO angles of 150-170 degrees. Spurred by the recent observation of such an angle in a square-pyramidal {FeNO}(7) complex, we carried out a density functional theory survey of 12 additional, largely hypothetical complexes with porphyrin and corrole analogues as equatorial ligands. Our calculations predict several instances of intermediate FeNO angles. The calculations further indicate a strong, positive correlation (R-2 = 0.9) between the FeNO angle and metal p character in the Fe de-based highest occupied molecular orbital.
