“…Recently, our group also reported five coordination polymers with 2-methyl-1H-imidazole-4,5-dicarboxylic acid (H 3 MIA) ligand [5][6][7][8][9]. The reported coordination polymers with H 3 MIA do not only show beautiful and interesting topological structures with various dimensionalities but also exhibit very flexible coordination modes [1][2][3][4][5][6][7][8]. To explore the effect of 2-position substituents of imidazole for dominating the self-assembly of metal-organic networks, we synthesised another new analogue ligand of 2-ethyl-1H-imidazole-4,5-dicarboxylic acid (H 3 EIDA), to prepare novel MOFs.…”
