METALLOPHILIC INTERACTIONS IN DOUBLE SALTS: TOWARD 1D METAL ATOM CHAINS

摘要

A new family of double sails has been developed that can display infinite one-dimensional chains of metallophilic interactions in the solid state. These salts are composed of cationic and anionic components that are designed to participate in metallophilic interactions with one another. These building blocks incorporate Au(III), Au(I), and Pt(II) atoms in the forms [L_3PtX]~+, [L_2AuX_2]~+, [AuX_4]~-, and [AuX_2]~-. Five different metallophilic structural motifs have been observed in these double salts and their monomeric precursors. The particular structure observed is affected by metal oxidation state, the electronic nature of the neutral (L) and anionic (X) substi-tuents, the synthetic conditions employed, as well as the solvent present.
