摘要:
Reaction of ferrocenyl carboxylate H(2)bfcs with Cd(Ac)(2) center dot 2H(2)O (H(2)bfcs = 1,1'-bis(3-carboxy-1-oxopropyl) ferrocene) gives the mononuclear tetrahydrate precursor Cd(Hbfcs)(2)(H2O)(4) (1). Investigation on the substitution reactions of 1 with imidazole or 2,2'-bpy afforded two one-dimensional (1D) complexes {[Cd-2(bfcs)(2)(C3H4N2)(6)] center dot 4H(2)O}(n) (2) and {[Cd(bfcs)(2,2'-bpy)(H2O)] center dot 2H(2)O}(n) (4) (2,2'-bpy = 2,2'-bipyridine), respectively. However, the one-step reactions of H(2)bfcs, Cd(Ac)(2) center dot 2H(2)O with imidazole or 2,2'-bpy result in the formation of two different 1D complexes {[Cd(bfcs)(C3H4N2)(2)] center dot CH3OH center dot 2H(2)O}(n) (3) and [Cd(bfcs)(CH3OH)](n) (5). It can be seen from the results that applying different synthetic routes produce dissimilar complexes from however the same materials and under the same reaction conditions. In addition, investigations of differential pulse voltammetry of these four 1D complexes indicate that their half-wave potentials are slightly higher than that of H(2)bfcs. (C) 2009 Elsevier B. V.
