We prepared and characterized the first example of a well-defined tungsten surface species that solely combines oxo and alkyl ligands. This represents a significant step toward the understanding of the WO3/SiO2 system, as we show that isolated organometallic metal oxide fragments give rise to high performance in propene metathesis.
