Using Cu(II), Mn(II) or Co(II) salt and the flexible ligands, N-[(4-carboxyphenyl)-sulfonyl]glycine (H3L1) and N-[(3-carboxyphenyl)-sulfonyl]glycine (H3L2), a series of new coordination polymers, [Mn(phen)(H2O)4][HL1] (1), [Co3(L1)2(bipy)3(H2O)6]n·8nH2O (2), [Cu4(L1)2(OH)2(bipy)4]n·12nH2O (3), [Na(H2L1)(H2O)]n (4), [Mn2(HL2)2(dpe)3(H2O)2]n·ndpe (5), (phen = 1,10-phenanthroline, bipy = 4,4′-bipyridine, dpe = 1,2-di(4-pyridyl)ethylene), varying from 0D to 3D, have been synthesized and structurally characterized. Compound 1 has a [Mn(phen)(H2O)4]2+ cation and a HL12- anion. Compound 2 features a new 1D triple chain, based on octahedral cobalt atoms bridged by bipy molecules and terminally coordinated by two H3L1 ligands. Compound 3 has a 2D layered structure, constructed from new alternating chains where H3L1, hydroxyl and water molecules simultaneously act as bridging ligands. Compound 4 possesses a bilayer structure in which two adjacent layers are pillared by H3L1 ligands into a 2D bilayer network. Compound 5 is a unique 3D coordination polymer in which each Mn center binds two trans-located dpe molecules. The thermal stability as well as magnetic properties of 5 was also studied. This work and our previous work indicate that the positional isomer of the anionic N-[(carboxyphenyl)-sulfonyl]glycine is important in the construction of these network structures, which are also significantly regulated by the metal centers.
