The unusual stability of [(OEP)ZrCH 2 SiMe 3 ] ( 1 ), which formally contains a Zr III center and is formed by reaction of [(OEP)Zr(CH 2 SiMe 3 ) 2 ] with H 2 , is best explained by considering two resonance structures, a Zr III metal‐based radical and a zwitterionic porphyrin radical anion. OEP (octaethylporphyrin) is denoted by a circle in the formulas shown on the right.
