三齿NS_2型配体Cu(Ⅱ)配合物的合成、光谱性质及电化学性质

SYNTHESIS, SPECTRAL AND ELECTROCHEMICAL PROTERTIES OF Cu(Ⅱ) COMPLEXES WITH TRIDENTATE NS 2 LIGANDS

蓝铜蛋白具有特征的光谱性质和异常的电化学性质因而受到人们的广泛重视［１，２］。为了阐述其结构与性质之间的关系，科学家们研究了一系列模型化合物，并且已取得了某些公认的结论［１］。然而，只有很少的配合物模拟了蓝铜蛋白ＥＳＲ谱中较小的超精细裂分Ａ‖值（３０...

A variety of complexes Cu(NS 2)(Im)(NO 3) 2 and Cu(NS 2)(Py)(NO 3) 2where NS 2=HN(CH 2CH 2SR) 2(R=CH 3CH 2CH 2, (CH 3) 2CH,CH 3CH 2CH 2CH 2 and (CH 3) 2CHCH 2), have been synthesized and characterized by elementary analyses, molar conductivity, IR, UV/Vis and ESR spectra as well as by electrochemical methods The new complexes exhibit exceptionally high redox potentials(500-580 mV) and complexes for HN(CH 2CH 2SCH(CH 3) 2) 2 exihibit rather hyperfine splitting constants( A ‖<70G) in the powder ESR spectra, which are close to those for the blue copper proteins
