摘要：Ten coordination compounds, namely {[Cd(L)(die)]center dot 2/3H(2)O}(n) (1), [Cd(L)(dib)](n) (2), [Cd(L)(bmimb)](n) (3), {[Cd(L)(bimb)]center dot 1/2EtOH)(n) (4), [Zn(L)(bimb)](n), (5), [Co(L)(bimb)](n) (6), {[Cd(L)(phen)]center dot EtOH}(n) (7), [Cu(L)(phen)](n) (8), [Zn(L)(mtpy)](n) (9) and [Ni(L)(mtPy)]-1/2H(2)O (10) (H2L = 4'-((2-carboxyphenoxy)methyl)biphenyl-2-carboxylic acid, die = 1,2-di(1H-imidazol-1-yl)ethane, dib = 1,4-di(1H-imidazol-1-yl)butane, bmimb = 1,4-bis((2-methyl-1H-imidazol-1-yl)methyl)benzene, bimb = 1,4-bis((1H-imidazol-1-yl)methyl)benzene, phen = 1,10-phenanthroline and mtpy = 4'-(4-methylphenyl)-2,2':6',2 ''-terpyridine), have been solvothermally synthesized. These compounds were characterized by X-ray crystallography, elemental analysis, infrared spectra (IR) and powder X-ray diffraction (PXRD). In compounds 1-3, similar dimeric [Cd-2(L)(2)] units are connected by different N-donor ligands to form diverse architectures. Strikingly, compound 3 displays a 2D -> 3D interdigitated framework. Compounds 4-6 are essentially isostructural and reveal 2D sheet structures. Compound 7 shows a 2D 4(4)-sql network stabilized by pi-pi interactions between the pyridine rings of the phen ligands. Compound 8 exhibits a 3D supramolecular architecture constructed from a 1D chain via pi-pi interactions. Compound 9 possesses a 1D chain structure, which is further extended into a 2D supramolecular layer through hydrogen-bonding interactions. Compound 10 displays a [Cd-2(L)(2)(mtpy)(2)] dimeric structure. Adjacent dimers further interact through hydrogen-bonding interactions to afford a 1D supramolecular chain. Moreover, the luminescent properties of 1-5, 7 and 9 have also been investigated in this work. (C) 2015 Elsevier Ltd. All rights reserved.
