R.sup.1 .sub.p Y.sub.q is provided. In this formula.alpha., .beta., p and q each is a number greater than zero,.alpha./.beta. = about 0.5 to 20,2.alpha. and 3.beta. = p + q,q/.beta. = about 0.5 to 1.5,Y is OR.sup.2 or OSiR.sup.3 R.sup.4 R.sup.5,R.sup.1, r.sup.2 and R.sup.3 each independently is a hydrocarbon radical having 1 to 20 carbon atoms, andR.sup.4 and R.sup.5 each independently is a hydrocarbon radical having 1 to 20 carbon atoms, hydrogen or a halogen atom.Said complex is prepared by reacting (A) an organomagnesium compound R.sup.1.sub.a M.sub.g X.sub.2-a wherein x is halogen, with (B) an aluminum compound AlYX.sub.2 wherein Y and X have the same meanings as above-defined. This method is superior to the prior art with respect to ease of reaction, high reaction efficiency and safety. Further the complex is safe during storage and handling. When the complex is employed as an olefin polymerization catalyst, the catalyst efficiency is higher and the characteristic properties of the resultant polymer are superior to those of polymers with other complexes.
