合成了4-硝基邻苯二硫酚配体及相应金属镍配合物,(Bu4N)2[M(nbdt)2](1)和(Bu4N)[M(nbdt)2](2)(nbdt=4-硝基邻苯二硫酚阴离子),并通过X-射线单晶结构测定、循环伏安、ESR谱、紫外可见吸收光谱和变温磁化率实验对其结构和性质进行了表征.这两个化合物均为略有变形的平面四方型配合物.配合物2是由配合物1通过I2氧化制备.配合物2含有一个未成对电子,磁性研究表明由于分子间的自旋耦合使它表现为反铁磁性.

Two new nickel complexes with a new 1,2-dithiolate ligand, (Bu4N)2[Ni(nbdt)2] (1) and (Bu4N)[Ni(nbdt)2](2) (nbdt=4-nitro-benzene-1,2-dithiolate), have been synthesized and characterized by X-ray single-crystal structure determination, cyclic voltammetry, ESR, UV/Vis spectra and magnetic susceptibility measurements. Complex 2 was obtained by oxidation of complex 1 with I2. The crystal structure determination reveals that the central Ni atoms in complexes 1 and 2 are in slightly distorted square-planar coordination environment. The cyclic voltammetric studies show that there are two oxidation peaks at 0.15 and 0.85 V for complex 1. The antiferromagnetic interaction dominates the magnetic properties in complex 2.
