Syntheses, Structures and Properties of 2D Metal-Organic Coordination Polymers Constructed from 5-Substituted Isophthalic Acid and Bis(imidazole) Ligands
Two new metal-organic coordination polymers, [Co_2(1,4-bib)_2(5-hipa)_2]_n(1)(5-H_2hipa=5-hydroxyisophthalic acid, 1,4-bib=1,4-bis(1-imidazolyl)benzene), [Co(Hbpt)(4,4′-bidpe)]_n(2)(H_3bpt =biphenyl-3,4′,5-tricarboxylic acid, 4,4′-bidpe=4,4′-bis(imidazol-1-yl)diphenyl ether) were obtained under solvothermal conditions and characterized structurally. The meta benzenedicarboxylates in 5-hipa~(2-) and Hbpt~(2-) connect the Co (Ⅱ) ions into 1 D carboxylate-cobalt chain structures with 8-membered ring Co_2O_4C_2...
