    • The synclinal and anticlinal diastereomers of the cyclometalated species are defined with respect to the orientation of the alkylidene substituents in the two possible alkylidene rotamers they are formed from (synclinal, alkylidene substituent pointing towards the Cp ligand; anticlinal, pointing away).
