    • Those systems should be officially referred to as (1),2,4-trisubstituted. However, the (1),3,5 method of numbering the Cp ring in this publication is adapted for historical reasons (researchers first prepared the 3-tert -butyl-substituted complex and then complexes having an additional substituent at the "5" position)
