Synthesis, Structure and Application of Intramolecularly-Coordinated Gallium Chalcogenides: Suitable Single-Source precursors for GaxSey Materials
Original language description
Studies have been focused on the synthesis of N -> Ga-coordinated organogallium selenides and tellurides [(LGa)-Ga-1(mu-Se)](2) (1), [(LGa)-Ga-2(mu-Se)](2) (2) and [(LGa)-Ga-1(mu-Te)](2) (3), respectively, containing either N,C,N- or C,N-chelating ligands L-1,L-2 (L-1 is {2,6-(Me2NCH2)(2)C6H3}(-) and L-2 is {2-(Et2NCH2)-4,6-tBu(2)-C6H2}(-)) having Ga/E (E=Se or Te) atoms in 1/1 ratio. To change the Ga/E ratio, an unusual NGa-coordinated organogallium tetraselenide (LGa)-Ga-1(kappa(2)-Se-4) (4) was prepared. An unprecedented complex ((LGa)-Ga-1)(2)(mu-Te-2)(mu-Te) (5), as the result of the non-stability of 3, was also isolated. Compound 2 is a suitable single-source precursor for the preparation of amorphous GaSe thin films by the spin coating. Moreover, simple heating of an octadecylamine solution of 2 provided, after work up, monoclinic Ga2Se3 crystals with different crystallinity according to conditions used. Therefore, compound 2 may be also used as a source of Ga2Se3 in the low-temperature doping process of Bi2Se3.
