合成了两种新的具有不对称三芳基三唑配体[L = 3-（对氯苯基）-4-（对甲基苯基）-5-（2-吡啶基）-1,2,4-三唑]的反式-[MnL2(NCS)2](1)和反式-[CoL2(H2O)(EtOH)]（ClO4)2·H2O(2)）配合物，并用元素分析、FT-IR、ESI-MS和单晶x射线衍射对其进行了表征。在配合物中，每个L通过吡啶基和三唑的氮采用螯合双齿模式。这两种配合物都具有类似的扭曲八面体核，在1中有两个NCS -离子在反位，而在2中有一个H2O和一个EtOH在轴位。
Two new complexes, trans-[MnL2(NCS)2] (1) and trans-[CoL2(H2O)(EtOH)](ClO4)2 · H2O (2) with asymmetrical triaryltriazole ligands [L = 3-(p-chlorophenyl)-4-(p-methylphenyl)-5-(2-pyridyl)-1,2,4-triazole], have been synthesized and characterized by elemental analysis, FT-IR, ESI-MS, and single-crystal X-ray diffraction. In the complexes each L adopts a chelating bidentate mode via the nitrogen of pyridyl and triazole. Both complexes have a similar distorted octahedral core with two NCS− ions in the trans position in 1, while one H2O and one EtOH are present in the axial sites in 2.
