Abstract
Six novel mixed-ligand complexes, [Cd(MCPA)2(bbhb)]n (1), [Cd(MCPA)2(bib)2]n (2), [Co2(MCPA)4(pbix)2] (3), [Zn(MCPA)2(pbix)2]n (4), [Cd(MCPA)2(obix)2]n (5), and [Co(MCPA)2(obix)2]n (6), have been synthesized under hydrothermal conditions and structurally characterized, where MCPAH = 2-methyl-4-chlorophenoxyacetic acid, bbhb = 1,1′-(1,4-butanediyl)bis-1H-benzimidazole, bib = 1,4-bis(imidazol-1-yl)-butane, pbix = 1,4-bis(imidazol-1-ylmethyl)benzene and obix = 1,2-bis(imidazol-1-ylmethyl)benzene. X-ray diffraction analyses reveal that the N-donor ligands bridge the metal centers into different 1 D chains in complexes 1, 2, 4, 5, and 6, while three is a dinuclear molecule containing 26-membered ring. Furthermore, the luminescent properties of 1, 2, 4, and 5 are also presented.
