Abstract
Three inorganic-organic supramolecular networks based on 2-[(4,6-dimethylpyrimidinyl)-2-thio] acetic acid (HL) and Zn(II), Ag(I) and Cu(II) salts have been prepared and structurally characterized by single-crystal X-ray diffractions. Mononuclear complex [ZnL2(1,2-DAP)]·2H2O (1) (1,2-DAP = 1,2-diaminopropane) exhibits a three-dimensional cavity architecture through hydrogen bonds and Ï-Ï interaction. The crystal structure of (AgL)n (2) consists of two-dimensional brick-wall framework. [Cu2L4(CH3OH)2]·3CH3OH (3) contains dinuclear copper units, which are bridged by four acetate groups. Electrochemical behaviors have been systematically investigated by different electrochemical methods. Complex 3 shows a pair of quasi-reversible redox peaks. The electrode process is controlled by diffusion. The diffusion coefficient (D) for 3 is about 10â6 cm2 sâ1. The electron transfer number (n) and the transfer coefficient (α) are 2 and 0.33, respectively.
