| 摘要: 合成了4-硝基邻苯二硫酚配体及相应金属镍配合物，(Bu4N)2[Ni(nbdt)2]
(1)和(Bu4N)[Ni(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。 |

| Abstract: 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. CCDC: 287714; 287715. |
