Crystal structure of catena-poly[triqua-bis(μ 2-4-carboxy-2-(1H-tetrazol-1-yl)-1H-imidazole-5-carboxylato-k3 N,O:O′)barium(II)] tetrahydrate, C14H14BaN12O15

“…It is well known that imidazole, tetrazole and their derivatives have been widely used as excellent building blocks for the preparation of complexes since they coordinate with most of metal ions with diverse coordination modes [4][5][6][7][8][9][10]. The N-heterocyclic carboxylic acid, 2-(1Htetrazol-1-methyl)-1H-imidazole-4,5-dicarboxylic acid and the deprotonated anions are excellent ligands as there are potential N-donors and O-donors.…”
