Theoretical evidence confirms the large influence that a Lewis acid (here BH 3 ) exerts on the type of H‐coordination in metallocene trihydrides (here [Cp 2 NbH 3 ]). The coordination of the Lewis acid facilitates both the formation of a dihydrogen structure ( 1 ) and the loss of a hydrogen molecule. This could be useful in the storage or elimination of molecular hydrogen using transition metal complexes.
