Note:
The hapticity is indicated as a superscript following the Greek letter \(\upeta\).
The hapticity is indicated as a superscript following the Greek letter \(\upeta\).
Example:
\(\ce{(C5H5)2Fe}\ (\rm{ferrocene})\) = \(\ce{bis(\upeta^{5}{-}cyclopentadienyl)iron}\), where \(\upeta^{5}\) can be read as eta-five or pentahapto.
