[H 2 LR, where H 2 stands for the two protons, the hydrazinic proton, and the phenyl proton at the ortho position, with respect to the imine function and R (R = OCH 3 , CH 3 , H, Cl, and NO 2 ) for the para substituent] with [Ru(PPh 3 ) 2 (CO) 2 Cl 2 ], carried out in refluxing ethanol, afforded monomeric complexes of type [Ru(PPh 3 ) 2 (CO)(HLR)(H)]. The crystal structure of the [Ru(PPh 3 ) 2 (CO)(HLNO
苯甲醛缩氨基硫脲的反应 [H 2 LR,其中 H 2 代表两个质子,即肼质子和邻位的苯基质子,相对于亚胺官能团和 R (R = OCH 3 , CH 3 , H, Cl,和 NO 2 ) 作为对位取代基] 与 [Ru(PPh 3 ) 2 (CO) 2 Cl 2 ],在回流乙醇中进行,得到 [Ru(PPh 3 ) 2 (CO)(HLR) 类型的单体配合物)(H)]。确定了[Ru(PPh 3 ) 2 (CO)(HLNO 2 )(H)] 络合物的晶体结构。缩氨基硫脲配体作为二齿 N,S-供体配体与钌中心配位,形成四元螯合环。当缩氨基硫脲与 [Ru(PPh 3 ) 2 (CO) 2 Cl 2 ] 在回流甲苯中进行反应时,[Ru2(PPh 3 ) 2 (CO) 2 (LR) 2 型二聚配合物家族] 获得。确定了[Ru2(PPh 3 ) 2 (CO) 2 (LCl) 2 ]的晶体结构。每个缩氨基硫脲配
