English abstract:
Transition metal silicides, especially iron and cobalt silicides, are of great interest because of their promising physical properties. Design of different shapes and sizes of those bulk materials offers new opportunities in thermoelectric, photovoltaic and catalytic applications. Due to this fact the current work is focused on nanoscaled iron and cobalt silicides. Zybill et al. proposed a mechanism for the gas phase decomposition of Fe(CO)4(SiCl3)2 involving an intermediate silylene complex formed by SiCl4 elimination, leading to iron silicide layers on a glass substrate. During re-investigation of this reaction, unexpected
formation of the new ionic complex [SiCl3(HMPA)3]+[Fe(CO)4SiCl3]− and a silylene-bridged complex Fe2(CO)6(μ2-SiCl2)3 was observed. Density functional theory calculations were carried out to elucidate possible elementary reaction steps.
