Mixed‐Ligand Metal‐Organic Frameworks: Synthesis and Characterisation of new MOFs Containing Pyridine‐2,6‐dimethanolate and Benzene‐1,4‐dicarboxylate Ligands

The development of synthetic approaches towards new mixed-ligand metal organic frameworks (MOFs) has been attracting considerable attention recently as they display fascinating properties due to the synergistic effect between different ligands. Herein, initial combination pyridine-2,6-dimethanol (H2pdm) with benzene-1,4-dicarboxylic acid (H2bdc) provided access three MOFs, [M3(bdc)2(Hpdm)2]n (MII=ZnII, 1; MnII, 2) and [Mn3(bdc)3(H2pdm)2]n (3). 1–3 are first MOFs containing H2pdm in its neutral or anionic form. 1 2 isostructural 2D a square lattice (sql) framework topology, while 3 is 3D MOF possessing primitive cubic (pcu) topology.
