Remarkable regioselectivity in the preparation of the first heterotrimetallic Mo[quadruple bond]W...Cr chain.
Addition of CrCl(2) to the dinuclear synthon MoW(dpa)(4) yields a regioselectively formed heterotrimetallic Mo[quadruple bond]W...Cr chain; computational studies suggest that the polarization of the Mo[quadruple bond]W quadruple bond partially accounts for this unexpected selectivity.
