Vanadium pyridine-imine complex having general formula (I), wherein : - R1, R2, R3, R4, R5 and R6, equal to or different from each other, represent a hydrogen atom; or are selected from linear or branched C1-C20 alkyl groups, preferably C1-C15, optionally halogenated, cycloalkyl groups optionally substituted, aryl groups optionally substituted; - X1, X2 and X3, equal to or different from each other, represent a halogen atom such as, for example, chlorine, bromine, iodine, preferably chlorine; or are selected from linear or branched C1-C20 alkyl groups, preferably C1-C15, -OCOR7 groups or -OR7 groups wherein R7 is selected from linear or branched C1-C20 alkyl groups, preferably C1-C15; - Y is selected from ethers such as, for example, diethylether, tetrahydrofuran (THF), dimethoxyethane, preferably is etrahydrofuran (THF); - n is 0 or 1. Said vanadium pyridine-imine complex having general formula (I) can be advantageously used in a catalytic system for the (co) polymerization of conjugated dienes.
