| چکیده مقاله |
| Pincer complexes support by pincer ligands with tridentate meridional geometry and good stability structure [1, 2]. Among different pincer ligands, the symmetric pincer ligands bearing two same lateral donor arms on the central donor unit have been synthesized in the early stage [1]. One of these ligands are P^N^P,s, classified in aliphatic or aromatic structure based on their backbone [2]. PNP pincer ligands that includ triazine backbone, and phosphorus coordinating group were broadly used in transition metal chemistry [3]. In this study, ruthenium pincer complexes {[Ru(PNP–Ph)Cl2(PPh3)] (1) based on PNP-Ph (N, N´-Bis(diphenylphosphino)-2,6-diamino-4-phenyl-1,3,5-triazine) was prepared. The pincer ligands and complexes were characterized by FT-IR, UV-Vis, 1H NMR, 13C NMR, and 31P NMR. The pincer complexes were used as a homogeneous electrocatalyst to CO2 reduction and Hydrogen evolution reaction in acetonitrile solution. electrocatalytical activity were recorded by cyclic voltammetry and chronoamrometry. Increasing purging time of CO2 from 5 to 30 min led to increase in current density, indicate progressive CO2 reduction process. |
