摘要：

A new family of cadmium(II) coordination polymers, {[Cd(Hbic)(2)center dot(H2O)(2)]center dot 2H(2)O}(n) (1), [Cd(Hbic)(2)](n) (2), [Cd(Hbic)(2)center dot (H2O)](n) (3), H(2)bic = 1H-benzimidazole-5-carboxylic acid, has been hydrothermally prepared by the assembly of Cd` with H(2)bic. A change in the pH values resulted in a series of compounds with different compositions and dimensionalities. Formed at the lowest pH, compound 1 has a two-dimensional supramolecular structure, which contains 1D chains ex- tended by hydrogen bonds. At a slightly higher pH, compound 2 is synthesized with a higher number of deprotonated carboxylate groups per cadmium atom. A further increase in the pH leads to 3D dinuclear compound 3 with yellow-green emitting fluorescence. ((c) Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007).
