Abstract
The design of multianionic chelating ligands as new organic linker for producing metal-organic frameworks (MOFs) is discussed. Three potentially polyanionic pro-ligands, 3,5-di-tert-butyl-2-hydroxy-N-(2-hydroxyethyl)-benzamide ((LH3)-L-1), bis(2-aminoethyl)-5-(tert-butyl)-2-hydroxyisophthalate ((LH3)-L-2a), and 5-(tert-butyl)-2-hydroxy-N1,N3-bis(1-hydroxy-2-methylpropan-2-yl)isophthalamide ((LH3)-L-2b), were synthesized and found to coordinate the osmyl ion in trianionic NO2 fashion through the N-amidate, O-phenolate, and O-alcoholate donor atoms. The X-ray crystal structures of three dioxo-Os(VI) complexes: [Os2O4(L-1)(2)(OH)K-2(H2O)(C3H6O)] (Os-1) [OsO2(L-2a(3-))-(MeOH)(4)(MeO)K-2] (Os-2a), and [OSO2(L-2b)(H2O)(C3H6O)K] (Os-2b) reveal that the osmyl moiety and the ligand establish distinctive interactions with the potassium ions, yielding unprecedented infinite network from stepladder chain (in Os-2b) and 2D-grid (in Os-1) to 3D-porous H-bonding network (in Os-2a).
