= 2; M = Fe, Co, n = 3) (Hmpo = 2-mercaptopyridine N-oxide) were prepared by reacting the appropriate metal chloride with either Nampo or dtpo [2,2-dithiobis(pyridine N-oxide)] in the presence of sodium methoxide. The structure of the complex Ni(mpo)2 was determined by X-ray diffraction. The nickel atom is in a square planar environment of two mpo− ligands in the cis configuration. The four complexes
配合物M(mpo)n(M = Mn,Ni,n = 2; M = Fe,Co,n = 3)(Hmpo = 2-巯基吡啶N-氧化物)的制备是通过使适当的金属氯化物与Nampo或dtpo [2,2-二硫代双(吡啶N-氧化物)]在甲醇钠存在下。通过X射线衍射确定复合物Ni(mpo)2的结构。镍原子是两个MPO的正方形平面环境-在配位体的顺式构型。通过理化方法,特别是通过1 H NMR光谱和循环伏安法研究了这四种配合物。
