A triangular gold(iminonitroxide-2-ide) trimer complex (5) was prepared and investigated to determine its magnetic properties. The results showed that the metalloid triradical is highly stable, even in solution under aerated conditions. The intramolecular exchange interaction of 5 was found to be positive (Jintra /kB ≈+29 K), thus showing that 5 is in a quartet ground state. In addition, a silver sandwich complex (5-Ag(+) -5) was prepared and its electronic and magnetic properties were also clarified.
一个三角型金（亚氨基-2-一）三聚物配合物（5）被制备并研究了其磁性。结果表明，这种类金属三自由基是高度稳定的，即使在有氧条件下的溶液中也是如此。发现 5 的分子内交换相互作用是正的（Jintra /kB ≈+29 K），因此表明 5 处于四重态基态。此外，还制备了一个银夹心配合物（5-Ag(+) -5），并阐明了其电子和磁性。
