Abstract

Thermal behaviour of the Fe2Ru(CO)12 bimetallic cluster on a SiO2 support was studied by FT-IR spectroscopy. At room temperature most of the molecules quickly decompose into Ru0(CO)2, RuII(CO)2 and RuIII(CO)2 species anchored to the silica surface, similarly to the behaviour of Fe2Ru(CO)12 on alumina. A smaller part (ca. 15%) of Fe2Ru(CO)12 is stable on the surface at room temperature in a distorted form. When heated in hydrogen and in vacuum a series of surface molecules has been identified: H2FeRu3(CO)13, H4FeRu3(CO)12, H4Ru4(CO)12, and HRu3(CO)10({A figure is presented}) anchored surface species. The ranges of thermal stability for the surface species have been given.
