Mono- and bis-silylated tellurium reagents in silver–telluride cluster synthesis: characterisation of Ag₃₀Te₂₁ and Ag₄₆Te₂₉ complexes

Abstract

AgCl, dissolved in ether solvents with tertiary phosphine ligands, reacts with a combination of the silylated reagents Te(SiMe₃)₂ and Te(R′)SiMe₃ (R′ = Ph, mes) to yield the cluster complexes [Ag₃₀(TePh)₁₂Te₉(PEt₂R)₁₂] (R = Et 1a, Ph 1b) and [Ag₄₆{Te(mes)}₁₂Te₁₇(PEt₃)₁₆] 2 in good yields; the molecular structures of 1a and 2 are described.
