Aerosol-assisted metallo-organic chemical vapour deposition of Bi2Se3 films using single-molecule precursors: the crystal structure of bismuth(m) dibutyldiselenocarbamate

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, 1H and 13C 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)

A novel supramolecular organic-inorganic adduct containing alpha-Keggin-type [PW12O40](3-) anions and benzo-15-crown-5 molecules

The structure of the title compound, tris(hydroxonium) 12- phosphato-tetracosa- 2-oxo-dodecaoxododecatungsten hexakis( benzo-15-crown-5)±methanol±water (1/1/1), (H3O)3- [PW12O40] 6C14H20O5 CH3OH H2O (where C14H20O5 is benzo-15-crown-5), has been determined at 180 K. [PW12O40]3ÿ anions are typical of -Keggin structures, and the [H3O (C14H20O5)2]+ sandwich-type moieties contain a large number of short O O close contacts, suggesting strong hydrogen bonding within them
