Development of synthetic method for seleno and telluronitrosyl complexes

用硒处理氮铼配合物，得到相应的硒亚硝酰基（NSe）配合物。通过初步X射线研究确定分子结构，以确认线性NSe配体。含三个二硫代氨基甲酸根配体的氮钼配合物与硒反应，导致二硫代氨基甲酸根配体分解，生成硫代亚硝酰基（NS）配合物。以CS_2为溶剂，反应生成了NS配合物和异硫氰酸根配合物。应该提到的是，S和CS是通过CS2在金属络合物中的还原歧化反应产生的，这是一个非常罕见的例子。具有刚性四阴离子型配体的氮钌配合物（其中氮是亲电配体）与硫的反应顺利地进行，得到相应的NS配合物，提供了晶体学表征的钌NS配合物的第三个实例。

When a nitridorhenium complex was treated with elemental selenium, the corresponding selenonitrosyl (NSe) complex was obtained. The molecular structure was determined by a preliminary X-ray study to confirm the linear NSe ligand. Reaction of nitridomolybdenum complex bearing three dithiocarbamato ligands, in which the nitrido ligand has a nucleophilic character, with selenium led to decomposition of the dithiocarbamato ligand leading to thionitrosyl (NS) complex. Using CS2 as a solvent in the reaction afforded the NS complex and isothiocyanato complex. It should be mentioned that S and CS were generated by reductive comproportionation of CS2 in a metal complex, demonstrating a very rare example. Reaction of nitridorutneium complex having a rigid tetraanion-type ligand, in which the nitrido is electrophilic ligand, with sulfur took place smoothly to give the corresponding NS complex, providing the third example of crystallographically characterized ruthenium NS complex.
