A new halide-free route to metallo-organic cadmium complexes; syntheses and structural characterisations of [Cd(PhCC)2(tmeda)] and [Cd(C12H8N)4]2–·2Li(thf)4+(tmeda = Me2NCH2NMe2)

Abstract

The syntheses of the monomeric diorganocadmium complex [Cd(PhCC)₂(tmeda)]1, the first structurally characterised Cd-acetylide, and of the ion-separated [Cd(C₁₂H₈N)₄]^2–·2Li(thf)₄⁺2, containing a metallo-organic Cd dianion, from the nucleophilic substitution reactions of Cd(NSiMe₃)₂ with PhCCLi (1 : 1 or 1 : 2 equiv.) and with C₁₂H₁₈NLi (1 : 1–4 equiv.) respectively, exemplify a new, halide-free and general route to metallo-organic complexes.
