Development of synthetic method for seleno and telluronitrosyl complexes

用元素硒处理硝基稀土络合物时，得到了相应的硒亚硝基(NSe)络合物。通过初步的X-射线研究确定了分子结构，确定了NSe的线形配体。含三个二硫代氨基甲酸配体的氮钼络合物与硒反应生成硫代氨基甲酰(NS)络合物，其中的二硫代氨基甲酸配体具有亲核性。以CS2为溶剂，反应生成NS络合物和异硫氰酸盐络合物。值得一提的是，S和CS是由CS2在金属络合物中还原同化生成的，这是一个非常罕见的例子。具有刚性四阴离子类型配体的硝基铀络合物与硫的反应顺利进行，得到了相应的NS络合物，提供了第三个结晶学表征的Ru NS络合物。

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.
