摘要:

Five coordination polymers,[Co(H3L)2(dib)]·1.5H2O(1),[Cu(H3L)2(dib)](2),[Co(H2L)(mtpy)]·DMF(3),[Ni(H3L)2(mtpy)(H2O)]·3DMF·H2O(4), and[Cd(H3L)2(pybim)]·1.5H2O(5), have been successfully prepared from 5,11,17,23-tetra-tert-butyl-25-(carboxymethoxy)calix[4]arene, metal salts, and N-donor auxiliary ligands under hy-drothermal conditions[dib=1,4-di(1H-imidazol-1-yl)butane, pybim=2-(2'-pyridyl)benzimidazole, and mtpy=4'-(4-methylphenyl)-2,2':6',2"-terpyridine]. Structural analysis suggests that the metal ion first joins two organic carboxylate ligands to form the independent units, which are further extended by the N-donor auxiliary ligand to give the final structure. Compounds 1 and 2 display 1D infinite chains bridged by a flexible bidentate dib ligand. Compounds 3-5, with multidentate chelate ligands, reveal discrete 0D units. Furthermore, in compounds 3 and 5, 1D supramolecular architectures are exhibited due to π-π interactions.
