Formation and calculations of the simple terminal triplet pnictinidene molecules n÷MF₃, P÷MF₃, and As÷MF₃ (M = Ti, Zr, Hf)

10.1021/ic900633k

The study focuses on the formation and calculations of simple terminal triplet pnictinidene molecules, specifically N÷MF3, P÷MF3, and As÷MF3, where M represents Ti (Titanium), Zr (Zirconium), and Hf (Hafnium). The researchers used laser-ablated atoms of Ti, Zr, and Hf and reacted them with NF3 (Nitrogen trifluoride), PF3 (Phosphorus trifluoride), or AsF3 (Arsenic trifluoride) to produce the triplet state terminal pnictinidene molecules. These molecules were trapped in an argon matrix and identified through infrared spectra and theoretical calculations. The purpose of using these chemicals was to investigate the formation and properties of these novel molecules, which are of interest due to their unique electronic structures and potential applications in understanding reactive intermediates and organometallic chemistry. The study aimed to understand the bonding interactions and stability of these molecules, providing insights into the weak π bonding between the pnictinidene elements (N, P, As) and the early transition metal group 4 elements (Ti, Zr, Hf).
