Abstract

Abstract : Temperature-dependent metalation of a new hexadentate enables the selective synthesis of both mononuclear ( i.e. kinetic product) and trinuclear ( i.e. thermodynamic product) complexes. Abstract : Temperature-dependent metalation of the new hexadentate ligand (tris(5-(pyridin-2-yl)-1 H -pyrrol-2-yl)methane; H3 TPM) enables the selective synthesis of both mononuclear ( i.e. Na(THF)4 [Fe(TPM)], kinetic product) and trinuclear ( i.e. Fe3 (TPM)2, thermodynamic product) complexes. Exposure of Na(THF)4 [Fe(TPM)] to FeCl2 or ZnCl2 triggers cluster expansion to generate homo- or heterometallic trinuclear complexes, respectively. The developed approach enables systematic variation of ion content in isostructural metal clusters via programmed assembly.
