Electron donation of common ligands
For example, an alkoxide, M-OR, can donate two to six electrons depending on the hybridization of the oxygen atom.
Accordingly, how many electrons does Cyclopentadienyl donate?
neutral counting: Fe contributes 8 electrons, the 2 cyclopentadienyl-rings contribute 5 each: 8 + 2 × 5 = 18 electrons.
In this way, how many electrons does no donate?
Using the neutral electron counting scheme, Cr has 6 d electrons and NO· has one electron for a total of 7.
Determine the total valence electrons (TVE) in the entire molecule (that is, the number of valence electrons of the metal plus the number of electrons from each ligand and the charge); say, it is A. Subtract this number from n × 18 where n is the number of metals in the complex, that is, (n × 18) – A; say, it is B.
