The paper presents the spectral analysis of cobalt(II) complexes with indoxyl thiosemicarbazone (ITSC) of general composition [CoL2X2] (where L=ITSC, X=Cl-, NO3-, (1/2)SO4(2-), NCS-). The geometry of the complexes have been characterized by elemental analysis, molar conductance, magnetic susceptibility measurements and spectral (electronic, IR, EPR, 1H NMR, mass) studies. The various physico-chemical techniques suggested a coordination number of six (octahedral) for chloro, nitrato and thiocyanato complexes. Whereas sulfato complex was found to have five coordinate trigonal-bipyramidal geometry. All the complexes are of high spin type showing magnetic moment corresponding to three unpaired electrons.
本文介绍了通式为[CoL2X2]（其中L =吲哚硫代半卡巴腙，X = Cl-、NO3-、(1/2)SO4(2-)、NCS-）的钴（II）与吲哚硫代半卡巴腙（ITSC）配合物的光谱分析。通过元素分析、摩尔电导率、磁化率测量和光谱（电子、红外、电子顺磁共振、1H核磁共振、质谱）研究对配合物的几何结构进行了表征。各种物理化学技术表明，氯、硝酸根和硫氰酸根配合物的配位数为六（八面体）。而硫酸根配合物被发现具有五配位三角双锥几何结构。所有配合物均为高自旋型，显示出对应于三个未成对电子的磁矩。
