N2 - 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 (1LH3), bis(2-aminoethyl)-5-(tert-butyl)-2- hydroxyisophthalate (2aLH3), and 5-(tert-butyl)-2-hydroxy- N1,N3-bis(1-hydroxy-2-methylpropan-2-yl)isophthalamide (2bLH 3), 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(1L)2(OH)K 2(H2O)(C3H6O)] (Os1), [OsO2(2aL3-)(MeOH)4(MeO)K 2] (Os2a), and [OsO2(2bL)(H 2O)(C3H6O)K] (Os2b) reveal that the osmyl moiety and the ligand establish distinctive interactions with the potassium ions, yielding unprecedented infinite network from stepladder chain (in Os2b) and 2D-grid (in Os1) to 3D-porous H-bonding network (in Os2a).
