Dear student
CO2+ ions can be easily oxidised to CO3+ ions because the crystal field stabilisation energy of Ci3+ ions with a d6 configuration is higher than d7 configuration.
In presence of ligand the d- orbitals of metal gets splits up into two set of orbitals that is t2g and eg. The half filled or fully filled t2g is more stable than other configuration. This is because it gives maximum amount of low energy of t29 orbital. Lower the energy more is the stabilisation.
