Abstract

Two-coordinate dialkylsilylene–coinage metal complexes <b>3</b><sup>+</sup>·TPFPB<sup>−</sup> (Cu) and <b>4</b><sup>+</sup>·TPFPB<sup>−</sup> (Ag) were synthesized as the first dialkylsilylene–copper complex and the first silylene–silver complex, respectively, by the reaction of dialkylsilylene <b>1</b> with the corresponding metal borate. X-ray analysis 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<sup>+</sup> and Ag<sup>+</sup> centers and responsible for the linear structures.
