Ta (ƞ5-C5H5)(CH3)3
d electron count at metal center = 5
oxidation state of the metal = 0
ligand contribution
ƞ5-C5H5 = 5 * 2 = 10
CH3 = 1 * 3 = 3

oxidation state of the metal = -1
ligand contribution
ƞ1-C3H5 = 1
PPh3 = 2
CO = 2*2 =4
Total electron count = 10+1+2+4+1 = 18 electrons
[Mn (ƞ6-C6H6)(CO)3]
d electron count at metal center = 7
oxidation state of the metal = +1
ligand contribution
ƞ6-C6H6 = 6
CO = 3*2 =6
Total electron count = 7+6+6-1 = 18 electrons
[Ru (PMe3)2(CHPh)Cl2]
d electron count at metal center = 8
oxidation state of the metal = +2
ligand contribution
(PMe3)= 2*2 =4
Cl = 2*1 =2
CHPh = 2
Total electron count = 8+4+2+2 = 16 electrons
[Co(µ2-CO)(CO)3]2
d electron count at metal center = 9
oxidation state of the metal = 0
ligand contribution
(µ2-CO)= 2
3CO = 3*2 =6
Metal-metal bond = 1
Total electron count = 9+2+6+1 = 18 electrons
At higher temperature a typical bond vibration is observed, The axial ligands of trigonal bipyramidal or square bipyramidal geometry exchange with the equatorial ones.
