Abstract
Herein we report on CO2 fixation by insertion into the Zn–N bonds of the two molecular compounds EtZnN(iPr)2 and EtZnN(iBu)2. The tetrameric carbamate complexes [EtZn(O2CNR2)]4 (R = iPr and iBu) were found to be the products of these reactions. The structures of the complexes were established by single-crystal X-ray diffraction. Thermal decomposition of the carbamate complexes was studied by applying a variety of different analytical techniques. These studies show that the compounds are suitable precursors for nanosized ZnO particles of ca. 10 nm diameter synthesised under mild conditions (< 200 °C) with the oxygen atoms originating from the reactant CO2.
