octahedral for Ni, square pyramidal for Cu, and square planar for Pt and Pd complexes. At the same time, the ligand L demonstrates the same coordination mode in all the complexes. It acts as a chelating ligand coordinated to the metal via two nitrogen atoms, namely the tetrazole ring N4 and the dimethylamino N atoms. Complex [PtLCl2] was found to have promising antiproliferative activity against human
摘要配合物[Cu2L2Cl4],[NiL2Cl2],[PdLCl2]和[PtLCl2],其中L是2-取代的5-(α-氨基烷基)四唑系列中的新型配体,即5-(N,N-二甲基氨基甲基)-2-叔丁基四唑已经合成并通过红外光谱,热分析和单晶X射线分析进行了表征。报道的配合物显示出金属的不同配位几何,即。Ni为八面体,Cu为方形锥体,Pt和Pd络合物为方形平面。同时,配体L在所有配合物中表现出相同的配位模式。它充当通过两个氮原子(即四唑环N4和二甲基氨基N原子)与金属配位的螯合配体。发现复合物[PtLCl2]对人宫颈癌细胞具有良好的抗增殖活性,IC50值是顺铂和卡铂之间的平均值。配合物[Cu2L2Cl4]的随温度变化的磁化率测量表明,铜(II)离子弱反铁磁耦合,耦合常数J为-2 cm-1。
