Kurzbeschreibung (Abstract)
The new 1,2-dithiooxalalo-bridged bimetallic Cu-Ga, Cu-In, and Cu-Sn complexes [[(Ph3P)(2)Cu(mu-S2C2O2)}(3)Ga] (1), [{(Ph3P)(2)Cu(mu-S2C2O2)}(3)In] (2), [(Ph3P)(2)Cu(mu-S2C2O2)In-(S2CNEt2)(2)] (3), and [{(Ph3P)(2)Cu(mu-S2C2O2)}(2)Sn(S2C2O2)] (4) were prepared and spectroscopically fully characterized. The crystal structures of 2-4 are presented. Complexes 3 and 4 are potential molecular single-source precursors (SSP) for the ternary semiconductors CuInS2 and Cu2SnS3, respectively, which can be manipulated under ambient conditions. Indeed, a study or the thermal degradation of 3 and 4 revealed that 3 affords pure nanoscaled CuInS2 (mean diameter ca. 2 rim) when the decomposition is carried out in an oleyla.mine solution by using a hot-injection or arrested-precipitation technique at temperatures well below 250 degrees C. In contrast, 4 decomposes under the same reaction conditions in an ambiguous mariner and forms mixed binary chalcogenide phases. This can be explained by a subtle influence of the relative stability of possible Sn-II and Sn-IV intermediates in the case of SSP [{(Ph3P)(2)Cu(mu-S2C2O2)}(2)Sn(S2C2O2)] (4).
