Preparation, characterization and ab initio computation of the first binary antimony azide, Sb(N3)3
摘要:
Reaction of SbI3 with silver azide in acetonitrile solution gave Sb(N-3)(3) in high yield. The product was separated from silver iodide by extraction with acetonitrile. The identity of this first binary antimony azide was established by N-14 NMR and IR spectroscopy. The molecular structure of Sb(N-3)(3) was computed ab initio at the Hartree-Fock (HF) level of theory (HF/6-31 + G*) using a quasi-relativistic pseudo-potential (ECP) for antimony. The calculated and observed IR frequencies are in reasonable agreement.
