Homoleptic ruthenium(III) chalcogenolates: a single precursor to metal chalcogenide nanoparticles catalyst

Eight homoleptic metal(III) arylchalcogenolate polymers [M(EPh-p-X)(3)](n) (M = Ru, Cr, and Mo) were characterized by PXRD. Structural solution of [Ru(SPh-p-tBu)(3)](n) 1 was achieved by Rietveld refinement of the PXRD data. Pyrolysis of [Ru(SePh)(3)](n) 4 produced nanostructured RuSe2, which selectively catalyzed the reduction of nitro compounds in the presence of other functionalities.
