dine-based metallotriazole complexes of ruthenium(II) monocarbonyls have been prepared and characterized. Both nitrosoguanidines prove to be strong chelates with the formally π-accepting nitroso nitrogen binding cis to carbon monoxide and a π-donating amide trans to the CO. The resulting ensemble consists of ruthenium examples of 1-metallo-2,3,5-triazoles. The ruthenium coordination sphere is completed
已经制备并表征了基于可溶性亚硝基胍和N-甲基亚硝基胍的钌 (II) 单羰基金属三唑配合物。两种亚硝基胍都被证明是强螯合物,形式上接受 π 的亚硝基氮顺式与一氧化碳结合,而 π 供体酰胺反式连接到 CO。由此产生的集合由 1-金属-2,3,5-三唑的钌实例组成. 钌配位球由阴离子(H –、Cl –或Ph – )、反式到亚硝基以及两个相互反式的PPh 3基团完成。π 供体酰胺基团形式上为 sp2与平面氮杂交,得到一个强结合的五元螯合阴离子。总之,这些结果说明了亚硝基胍盐作为一类新型金属螯合物的巨大潜力。
