Popis:	Hemilabile tris( -butoxy)silanolate ligands allow stabilizing a mononuclear octahedral Mo( ) complex without quenching its reactivity towards small molecules (N , CO , N O). Coordinatively unsaturated Mo( ) complexes have been identified as highly reactive species able to activate dinitrogen without the need for a sacrificial reducing agent. Here, we report a coordinatively saturated octahedral Mo( ) complex stabilized by κ -tris( -butoxy)silanolate ligands, which is yet highly reactive towards dinitrogen and small molecules. The combined high stability and activity are ascribed to the dual binding mode of the tris( -butoxy)silanolate ligands that allow unlocking a coordination site in the presence of reactive small molecules to promote their activation at low temperatures.
