Abstract: An intermetallic compound is disclosed. The compound is formed by reacting a first reaction product, the first reaction product being the product of reaction of a polymeric transition metal oxide alkoxide with a reducing metal having a higher oxidation potential than the transition metal, the polymeric transition metal oxide alkoxide being the product of the controlled partial hydrolysis of a transition metal alkoxide, with a first halide activator to produce a second reaction product.
