title: Intramolecularly Coordinated Gallium Sulfides: Suitable Single Source Precursors for GaS Thin Films.
abstract: Our studies have been focused on the synthesis of N→Ga coordinated organogallium sulfides [L1Ga(μ-S)]3(1) and [L2Ga(μ-S)]2(2) containing either N,C,N- or C,N-chelating ligands L1or L2(L1is {2,6-(Me2NCH2)2C6H3}-and L2is {2-(Et2NCH2)-4,6-tBu2-C6H2}-). As the result of the different ligands, compounds 1 and 2 differ mutually in their structure. To change the Ga/S ratio, unusually N→Ga coordinated organogallium tetrasulfide L1Ga(κ2-S4) (3) was prepared and the unprecedented complex [{2-[CH{(CH2)3CH3}(μ-OH)]-6-CH2NMe2}C6H3]GaS (4) was also isolated as the minor by-product of the reaction. Compounds 1-3 were further studied as potential single-source precursors for amorphous GaS thin film deposition by spin-coating.
