Oxo-nitrogenated iron complex having general formula (I): in which: R1 and R2, identical or different, represent a hydrogen atom; or they are selected from linear or branched, optionally halogenated C1 - C20, preferably C1-C15, alkyl groups, optionally substituted cycloalkyl groups, optionally substituted aryl groups; R3 represents a hydrogen atom, or it is selected from linear or branched, optionally halogenated C1 - C20, preferably C1 - C15 alkyl groups, optionally substituted cycloalkyl groups, optionally substituted aryl groups; X, identical or different, represent a halogen atom such as, for example, chlorine, bromine, iodine, preferably chlorine; or they are selected from. linear or branched C1 -C20, preferably C1 - C15, alkyl groups, -OCOR4 groups or -OR4 groups in which R4 is selected from linear or branched C1 - C20, preferably C1 - C15, alkyl groups; n is 2 or 3. Said oxo-nitrogenated iron complex having general formula (I) can be advantageously used in a catalytic system for the (co)polymerization of conjugated dienes.
