the cationic complexes were isolated with chloride/PF6 as the counter ion. Reactions of rhodium and iridium dimers with L2 yielded neutral complexes 5 and 6 with the general formula [(arene)M(L)Cl2]. The neutral complexes 5 and 6 were further reacted with NaN3 to yield azido complexes 10 and 11. These complexes were, in turn, reacted with acetylene derivatives to yield triazolo complexes 12–15 where
一系列配合物(1 - 9)通过卤化物反应合成桥与三个吡嗪硫脲的金属前体配位体L1,L2和L3,得到阳离子以及中性配合物和其特征在于,各种光谱技术。阳离子络合物由通式[(亚芳基)M(L)Cl] +表示,其中L = L1,L2和L3,芳烃= 对甲基异丙基苯,Cp *和M = Ru,Rh和Ir。用氯离子/ PF 6作为抗衡离子分离所有阳离子配合物。铑和铱二聚体与L2产生具有通式[(亚芳基)M(L)Cl 2 ]的中性配合物5和6。使中性络合物5和6与NaN 3进一步反应以产生叠氮基络合物10和11。这些复合物,反过来,用乙炔类反应生成三唑配合12 - 15只有Cp的几个三唑复合物*已经被报道。X射线衍射研究表明,该配合物在金属中心周围具有典型的钢琴凳几何形状,并且硫脲加合物以螯合(N,S)方式与金属中心结合。此外,配合物筛选1 – 9以及配体中潜在的抗菌剂,其中配合物3和5具有抗菌活性。比色传
