    The M−C π-bond in metal carbonyl which is formed by the donation of an electron pair from a filled d-orbital of metal into the vacant antibonding π-orbital of CO, strengthens the M−C σ-bond. This is called synergic effect and is usually observed in metal carbonyls.

    Metal carbonyls gain some extra stability due to the formation of synergic bonds. These synergic bonds are formed by lone pair electrons of central metal and... Vaccant anti bonding pi orbitals of carbonyl. This makes shortening of metal carbonyl bond so becomes stronger..... And lengthening of carbon oxygen bond of carbonyl.
