N2 - The triruthenium complexes containing alkynols ligands have been reacted with 2(diphenylphosphino)ethyl-triethoxysilane (dpts), obtaining novel chemically stable disubstituted complexes. The same disubstituted Ru complexes above described were also synthesized following another approach based on the reaction from the phosphine substituted complex Ru3(CO) 10(dpts)2 and the same alkynols ligands used to obtain the above triruthenium complexes. One of these stable complexes, the HRu 3(CO)7[C≡C(Me)2(OH)](dpts)2 compound was grafted on the mesoporous silica SBA-15 and on γ-Al 2O3 surface in order to obtain novel hybrid materials to employ in heterogeneous catalysis. The resulting materials have been characterized by multidisciplinary approach based on inductively coupled plasma-mass spectrometry (ICP-MS), FT-IR, XRD, physisorption measurements and DR-UV-Visible spectroscopy.
