The invention is directed towards a composition comprising the formula LMX(X')n wherein n equals 0 or 1; X and X' are independently selected from the group consisting of halides, hydride, triflate, acetates, borates, C1 through C12 alkyl, C1 through C12 alkoxy, C3 through C12 cycloalkyl, C3 through C12 cycloalkoxy, aryl, thiolates, carbon monoxide, cyanate, olefins, and any other moiety into which a monomer can insert; M is selected from the group consisting of nickel, palladium, and platinum and L is a nitrogen-containing bidentate ligand with more than two nitrogen atoms. The composition possesses a tetrahedral or pseudo-tetrahedral structure. The invention also provides a method for using the composition in conjunction with an activating cocatalyst to form short chain α-olefins.
