coordination about the copper, with an equatorial N 2 S 2 donor set, plus the third thioether sulfur bound axially. The most marked consequence of the pyridine α-methylation is that the Cu 2+/+ reduction potential is raised by about 200 mV; otherwise, the E 1 2 is consonant with previously advanced models for correlating redox potentials with ligand structural features. The pyridyl copper(II) complexes have
摘要线性四齿配体1,8-双(2'-喹啉基)-3,6-二硫辛烷和三个五齿配体1,9-双(2'-吡啶基)-2,5,8-三噻喃烷,1,9已经制备了-双(6'-甲基-2'-吡啶基)-2,5,8-三噻烷烷和1,11-双(2'-喹啉基)-3,6,9-三噻烷十一烷。深绿色-蓝色铜(II)螯合物已通过光学和ESR光谱和循环伏安法进行了表征。两种吡啶基螯合物对铜具有相似的四方配位,具有赤道的N 2 S 2供体,加上轴向键合的第三硫醚硫。吡啶α-甲基化的最显着结果是Cu 2 + / +还原电位提高了约200 mV。否则,E 1 2与先前将氧化还原电势与配体结构特征相关的先进模型相吻合。
