geometries for all nickel centers. Three of the four complexes are dimers with chloride bridges between the two Ni(II) ions. However, in solution all complexes have a monomeric formulation, based on mass spectrometry and osmometry measurements. The complexes were also screened for their cytotoxic activity on human cell lines (HeLa, SK-LU-1 and HEK-293), and compared with a related Cu(II) complex.
合成了四种具有双(苯并咪唑)硫基和硒醚基配体的新型镍(II)配合物,并通过元素分析,红外,磁化率和X射线晶体学表征了其固态,并通过FAB +质谱在溶液中对其进行了表征,紫外可见光谱和循环伏安法。化合物的单晶X射线衍射分析显示了所有镍中心的八面体几何形状。四个络合物中的三个是在两个Ni(II)离子之间具有氯桥的二聚体。但是,在溶液中,基于质谱和渗透压测量,所有配合物均具有单体配方。还筛选了复合物对人细胞系(HeLa,SK-LU-1和HEK-293)的细胞毒活性,并与相关的Cu(II)复合物进行了比较。
