similar condition gave a dinuclear ruthenium phosphine complex [(η6-p-cymene)Ru(μ-Cl)3RuCl(κ2-P,P-L2)] (2). Complexes 1 and 2 were characterized by microanalyses, IR and NMR spectroscopies, and their structures were also established by single-crystal X-ray diffraction. Immobilization of complexes 1 and 2 on SBA-15, and characterization of these hybrid heterogeneous catalysts were studied by transmission
