  Synthesis, temperature-controlled structures and polyphenol oxidase activities of dinuclear manganese(II) complexes with N,N,N′,N′-tetrakis(2′-benzimidazolylmethyl)-1,4-diethylene amino glycol ether

  摘要：

  Three dinuclear Mn(II) complexes, [Mn-2(EGTB)(NO3)(2)(H2O)(4)](NO3)(2) (1), [Mn-2(EGTB)(NO3)(4)] (2) and [Mn-2(EGTB)(NO3)(H2O)](NO3)(3) (3) (EGTB = N,N,N',N'-tetrakis(2'-benzimidazolylmethyl)-1,4-diethylene amino glycol ether) were prepared and characterized. Their crystal structures revealed a relationship between synthesis temperature and structure. With increasing the reaction temperature from 60 to 120 degrees C or 160 degrees C, the Mn-Mn distances are shortened from 14.019 angstrom in 1, 7.662 angstrom in 2 to 5.662 angstrom in 3. Additionally, polyphenol oxidase (PPO) activity of those three complexes was studied by measuring the rate of increase in absorbance at 320 nm of pyrogallol substrate. At pH 7.8 and 30 degrees C, the turnover numbers are 5.58 h (1) for 1, 11.38 h (1) for 2 and 13.97 h (1) for 3, respectively. Furthermore, in pH 7.8-8.2, their catalytic activity increased with rising pH. (C) 2012 Elsevier B. V. All rights reserved.
