Synthesis, crystal structures, and electronic spectra of (1,8-naphthyridine)ReI(CO)3Cl and [(1,8-naphthyridine)CuI(DPEPhos)]PF6
Sprache des Titels:
wo 1,8-naphthyridine (nap) metal complexes (nap)ReI(CO)3Cl (1) and [(nap)CuI(DPEPhos)]PF6 (2) were synthesized and characterized by NMR-, emission, and absorption spectroscopy, elemental analysis, mass spectrometry, and X-ray structural analysis. In both complexes, the nap ligand coordinates with both N atoms to the metal centre in a bidentate manner. 1 and 2 exhibit a broad phosphorescence in solid state at T = 300 K, which is completely quenched in solution at r.t. In addition, the gas-phase structures of both complexes were optimized at the B3LYP/6-31G(d,p) level of theory.
