Description |
The synthesis and characterization of substituted benzimidazolin-2-selones (4c-4d) and -tellone (4i) are reported. Upon reaction with halogens (I-2, Br-2, and Cl-2), these selones and tellone yield dihaloselones/tellone (5c-5i). The reaction of dihaloselones with elemental tellurium/tin/bismuth leads to the formation of selone-coordinated monomeric tellurium tetrahalides, tellurium dibromide (8), tin tetrahalides, and bismuth triiodide adducts (7a-7g), respectively. The structures of the tellurium tetrahalide (7a, 7d, and 7g), tellurium dibromide (8), tin tetrahalide, and bismuth triiodide adducts have been established by single-crystal X-ray analysis. The bismuth triiodide adduct is the first neutral tetrameric structure with selones. The bismuth adduct has been used as a single-source precursor for the synthesis of bismuth selenide (Bi2Se3) nanoparticles, which were characterized by powder XRD patterns. The TEM images show the hexagonal shape of the nanoparticles.
