Abstract
Two-coordinate dialkylsilylene-coinage metal complexes 3+·TPFPB-(Cu) and 4+·TPFPB-(Ag) were synthesized as the first dialkylsilylene-copper complex and the first silylene-silver complex, respectively, by the reaction of dialkylsilylene 1 with the corresponding metal borate. X-ray analys is showed that both the complexes adopted a linear structure with two perpendicular dialkylsilylene units. Theoretical study indicated that weak π back-donation of the copper and silver complexes compared to that of the corresponding isoelectronic neutral palladium complex would be due to low-lying d orbitals of Cu+and Ag+centers and responsible for the linear structures.
