Abstract
Dinitrogen complexes have garnered significant attention due to their potential applications across various fields. The synthesis and characterization of novel dinitrogen complexes are essential to advancing this area of research. In this study, we report the bulk synthesis and first successful single crystal X-ray structure analysis of [Cr(PCy3)2(CO)3(N2)] using high-pressure nitrogen at 50 atm. The presence of the nitrogen ligand was confirmed by infrared (IR) spectroscopy and elemental analysis, and the interesting disorder phenomenon between N2 and CO ligands was also observed. The elimination process of the N2 ligand was monitored by a combination of thermogravimetry (TG) and temperature-programmed desorption (TPD), and the changes in the color, IR spectrum, and UV–vis spectrum of the complexes before and after elimination were investigated. These experimental results agree well with the results of density functional theory (DFT) calculations.
期刊介绍:
Organometallics is the flagship journal of organometallic chemistry and records progress in one of the most active fields of science, bridging organic and inorganic chemistry. The journal publishes Articles, Communications, Reviews, and Tutorials (instructional overviews) that depict research on the synthesis, structure, bonding, chemical reactivity, and reaction mechanisms for a variety of applications, including catalyst design and catalytic processes; main-group, transition-metal, and lanthanide and actinide metal chemistry; synthetic aspects of polymer science and materials science; and bioorganometallic chemistry.
