Crystal Structure, thermal study, vibrational and optical properties of a novel dinuclear Bismuth(III) Iodide trimethylenedipyridine compound
Résumé
Bismuth-based materials have stimulated much interest due to their unique
photoluminescence behavior. To date, several luminescent bismuth (III) complexes ligated by
N-donor ligands have been investigated. In this work, a new luminescent binuclear
compound built from BiI 3 with a pyridine-type ligand, synthesized in MeOH solution and
crystallized under slow evaporation method. This halide-bridged binuclear compound, which
is also doubly bridged by 4,4’-trimethylenedipyridine, was characterized through single
crystal X-ray diffraction at 100 K. Its thermal behavior was investigated via TGA-DTA, as
well as its vibrational spectra by Infrared and Raman spectroscopy. Furthermore, the
photoluminescence properties were examined through steady-state and time-dependent
luminescence techniques.
