Using DFT methods we describe the fluxional behavior of mono-, bi-, and tripodal W(CH3)(6) species grafted on partially dehydroxylated silica. Our results show that the umbrella inversion mechanism described to explain the fluxionality of the parent W(CH3)(6) molecule is not operative after grafting on silica. Low-energy turnstile rotations are instead operative for all considered species, correlating the experimental values found in solid-state NMR.

Abstract

Using DFT methods we describe the fluxional behavior of mono-, bi-, and tripodal W(CH3)(6) species grafted on partially dehydroxylated silica. Our results show that the umbrella inversion mechanism described to explain the fluxionality of the parent W(CH3)(6) molecule is not operative after grafting on silica. Low-energy turnstile rotations are instead operative for all considered species, correlating the experimental values found in solid-state NMR.
