Abstract

An antimony (III) selone complex was synthesized starting from the corresponding imidazole selone IPr*Se. This newly isolated Sb (III) complex was fully characterized by NMR, FT-IR, TGA and single crystal X-ray diffraction techniques. In a solid state structure the IPr*Se depicts a rare coordination mode. The molecule is a neutral binuclear antimony (III) selone with Sb:Se ratio of 2:1. Notably the Sb-Se bond length is slightly longer than expected, due to the sterically superbulky ligand. Besides the Sb---π aryl interactions was observed in the molecular packing. The antimony (III) selone represents the first example of metal selone reported with unusual coordination mode of imidazole selone. In addition, the photophysical properties of IPr*=Se and antimony (III) selone were investigated and compared.
