Homework Answers
The whole coordination sphere is same just 
-C5H5
has been replaced by -C5Me5
in the second complex. Now cyclopentadienyl moiety is e- donor
ligand . Changing the substituent of H by Me increases the e-
density in the ligand as well as thus in Fe centre also. Now look
over the rest of the ligands which are PMe3 and CO which
are e- withdrawing type. In 2nd complex e- density over the metal
is higher so e- will be much more attracted by both PMe3
and CO . Thus increasing the bond order between metal and this
ligands. Thus Fe-P bond length will become shorter in 2nd
complex.

Which complex would you expect to have longer Fe-P bonds,
(η5-C5H5)Fe(Cl)[PMe3)(CO)
or
(η5-C5Me5)Fe(Cl)[PMe3)(CO)?
