    Abstract: Organometallic complex having the formula (IAP)M(X)n which can be used for die formation of catalytic systems wherein: M is a metal selected from transition metals and lanthanides, in oxidation state “s” positive and different from zero; each X is independently a group of an anionic nature bound to the metal as an anion in an ionic couple or with a convalent bond of the “&sgr;” type; “n” expresses the number of X groups sufficient for neutralizing the formal “+s” charge of the metal M, and (IAP) represents a neutral bond consisting of a mono-imine of 2,6-diacylpyridine. Said complex is prepared with relatively simple methods and can be used, combined with a suitable co-catalyst, such as for example, an aluminoxane, as a catalyst in normal (co)polymerization processes of &agr;-olefins, and especially ethylene.
