ABSTRACT

The Zn(TeC6H2Me3-2,4,6)2 or C18H22Te2Zn [bis(2,4,6-trimethylbenzenetellurolato) zinc] quaternary compound is formed in this system. To obtain this compound, Zn[N(SiMe3)2]2 was added via syringe to a cold [−30°C (Bochmann et al. 1997); −78°C (Bochmann et al. 1995)] solution of 2,4,6-trimethylbenzenetellurolato in light petroleum prepared in situ from (2,4,6-Me3C6H2Te)2 (Bochmann et al. 1995, 1997). A white to pale beige solid precipitates from the reddish solution. The mixture was stirred at −10°C for 4 h [at −78°C for 30 min (Bochmann et al. 1995)], allowed to warm to room temperature, and ltered. The colorless residue was washed with warm toluene and light petroleum (2 × 20 mL) [with light petroleum ether (3 × 30 mL) (Bochmann et al. 1995)] and dried in vacuo to give an off-white to beige microcrystalline solid, which melts with decomposition at 224°C-225°C (Bochmann et al. 1997). The reaction was carried out under inert gas using standard vacuum-line techniques. Heating a solution of C18H22Te2Zn in mesitylene leads to formation of ZnTe (Bochmann et al. 1995, 1997). The thermolysis of this compound in reuxing 4-ethylpiridine proceeded more slowly giving nanoscale particles of ZnTe (Bochmann et al. 1995).
