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.
