Charge Of Co Ligand. The complex ion carrying a positive charge is called cationic complex and the one with a negative charge is called anionic complex. Weve recently seen that there are really two bonding interactions at play in the carbonyl ligand. In rare cases CO 2 binds to metals as a Lewis base through its oxygen centres but such adducts are weak and mainly of theoretical interest. Ligand to Metal Charge Transfer LMCT involving an octahedral d6 complex.

This leaves the C p y orbital empty and the O p y orbital doubly occupied and so the second π. The complex ion carrying a positive charge is called cationic complex and the one with a negative charge is called anionic complex. A metalCO bonding interaction thus comprises of a CO to metal σdonation and a metal to CO πback donation Figure 1. In this example the cyanide ligands are innocent ie they have a charge of 1 each 5 total.
Because of that a ligand substitution reaction can be easily driven to the right side by purging CO out of the reaction vessel.
CoNH 3 6 3 CuNH 3 4 2 AgCN 2 FeC 2 O 4 3 3-etc. This leaves the C p y orbital empty and the O p y orbital doubly occupied and so the second π. Ligand to metal charge transfer results in the reduction of the metal. The overall charge can be positive negative or neutral. Valence BondDescription of the CO ligand In the CO molecule both the C and the O atoms are sp hybridized. A metalCO bonding interaction thus comprises of a CO to metal σdonation and a metal to CO πback donation Figure 1.
