series of fourteen octahedral nickel(IV) dithiocarbamato complexes of the general formula [Ni(ndtc)3]X·yH2O ndtc stands for the appropriate dithiocarbamate anion, X stands for ClO4− (1–8; y = 0) or [FeCl4]− (9–14; y = 0 for 9–12, 1 for 13 and 0.5 for 14} was prepared by the oxidation of the corresponding nickel(II) complexes, i.e. [Ni(ndtc)2], with NOClO4 or FeCl3. The complexes, involving a high-valent
通式[Ni(n dtc)3 ] X · y H 2 O n dtc的十四个八面体镍(IV)二硫代氨基甲酸酯配合物系列代表适当的二硫代氨基甲酸酯阴离子,X代表ClO 4 -((1 – 8 ; Ý = 0)或[的FeCl 4 ] - (9 - 14 ; Ÿ = 0 9 - 12,1 13和0.5 14}通过用NOClO 4或FeCl 3氧化相应的镍(II)配合物,即[Ni(n dtc)2 ]来制备。通过元素分析(C,H,N,Cl和Ni),UV-Vis和FTIR光谱,热分析以及磁化学和电导率测量,对涉及高价Ni IV S 6核的配合物进行了表征。确定了[Ni(hmi dtc)3 ] [FeCl 4 ](9)的X射线结构它由共价离散的复合物[Ni(hmi dtc)3 ] +阳离子和[FeCl 4 ] -组成阴离子},这分别揭示了复杂阳离子和阴离子中八面体和四面体的几何形状略有变形。Ni(
