Abstract

Metal-selenides have got vast applications in the field of metallurgy. In particular, the zinc selenide material is one of the most important materials that show excellent optical applications. In general, ZnSe is prepared by hydrothermal methods while the soft approach to prepare this material is limited, whereby Zn:Se ratio can be effectively controlled. Thus, a new 3,3’-methylenebis(1-isopropyl-1H-imidazole-2(3H)-selenone (3) ligand has been prepared by the reaction of 3,3’-methylenebis(1-isopropyl-1H-imidazole-3-ium) bromide and methyl bromide. The new zinc selenide complex has been prepared from the reaction of zinc tetrafluoroborate and (3), where one Zn is coordinated to four Se centres. The selenone ligand and the ZnSe complex have been characterized thoroughly by 1H NMR, 13C NMR, FT-IR, solution UV-vis and single crystal X-ray diffraction techniques. The thermal stability of the zinc selenide is also studied by TGA. In addition, novelbisimidazoselenone ligand with ethyl spacer and imidazoselenone ligand with biphenyl spacer have been prepared and characterized by 1H NMR, 13C NMR, FT-IR, solution UV-vis and single crystal X-ray diffraction techniques
