Aerosol-assisted metallo-organic chemical vapour deposition of Bi2Se3 films using single-molecule precursors. The crystal structure of bismuth(III) dibutyldiselenocarbamate

resumo

The complexes [Bi{Se2CN(C2H5)(2)}(3)], [Bi{Se2CN(C4H9)(2)}(3)], [Bi{Se2CN(CH3)(C4H9)}(3)] and [Bi{Se2CN(CH3)(C6H13)}(3)] have been synthesized and characterized structurally using IR, H-1 and C-13 NMR. In addition, the crystal structure of [Bi{Se2CN(C4H9)(2)}(3)] was determined by single-crystal X-ray diffraction, showing the bismuth centre coordinated to three dialkyldiselenocarbamate ligands through the selenium donor atoms. The Bi(III) compounds were used as precursors for the deposition of Bi2Se3 films on glass substrates through aerosol-assisted metallo-organic chemical vapour deposition (AA-MOCVD).
