Functionalization of [Re6Q8(CN)6]4− clusters by methylation of cyanide ligands†
Abstract
Methylation of anionic cluster complexes [Re6Q8(CN)6]4− with ((CH3)3O)BF4 or CF3SO3CH3 afforded homoleptic isonitrile cluster complexes [Re6Q8(CH3NC)6]2+ (Q = S, Se, Te). The clusters were characterized by X-ray crystallography, mass spectrometry, 1H NMR, 13C NMR, 14N NMR, 15N NMR, 77Se NMR, and 125Te NMR techniques, electrochemistry, TGA, and photophysical measurements.
