Abstract

Reaction of phenylisothiocyanate with different aromatic amines allowed the synthesis of compounds containing the thiourea moiety. By reacting silver bis(triphenylphosphine)nitrate with suitable ligands belonging to this family of sulphurated compounds, three new complexes have been afforded. Ligands and complexes were characterized also by X-ray diffraction. The structures reveal remarkable differences in the silver coordination geometry in function of the nature and size of the ligand. The emission properties of all compounds were characterized at 10 and at 298 K.

Graphical abstractThioureic ligands (Phpytu (1), Phmepytu (2), Phflotu (3), phenylpyridyl-, phenylmethylpyridyl- and phenylfluorenyl-thiourea, respectively) and their phosphinic silver(I) complexes have been synthesized and characterized also by X-ray diffraction. Upon different experimental conditions and changing the ligands flexibility, the coordination geometry, affected also by the presence of nitrate group, varies from tetrahedral to trigonal. The luminescence behaviour of all compounds was studied.Figure optionsDownload full-size imageDownload as PowerPoint slide
