the copper sites in proteins, model copper(II) complexes of two multidentate ligands with nitrogen and sulfur atoms, 1,5-bis(2-pyridylmethylamino)-3-thiapentane (pmtp) and 2,6-bis(2,6-dithiaheptyl)pyridine (dthp), have been isolated as [Cu(pmtp)][Cu(pmtp)ClO4](ClO4)3 (1) and [Cu(dthp)(NO3)2] (2), respectively, and studied by X-ray diffraction, spectroscopic, and electrochemical methods. Complex 1 crystallizes
为了了解影响蛋白质中铜位点化学性质的因素,模拟了两个具有氮和硫原子的多齿配体的铜 (II) 配合物,即 1,5-双(2-吡啶基甲基氨基)-3-硫戊烷 (pmtp ) 和 2,6-双(2,6-二硫庚基)吡啶 (dthp),已分离为 [Cu(pmtp)][Cu(pmtp)ClO4](ClO4)3 (1) 和 [Cu(dthp)( NO3)2] (2) 分别通过 X 射线衍射、光谱和电化学方法进行研究。配合物 1 在具有四个 [Cu(pmtp)]2+ 离子和四个 [Cu(pmtp)(ClO4)]+ 离子的单斜晶系的空间群 P21/a 中结晶,尺寸为 a = 24.180(7), b = 31.855(7), c = 9.760(3) A, β = 143.84(1)°。两个独立配合物中铜周围的配位分别是方锥体和八面体,分别带有一个胺氮,两个吡啶氮,
