Approaches to the synthesis of organic aurophilic ligands, viz., sulfur-containing 2,2′:6′,2'-terpyridine derivatives, were developed. Complexation reactions of the terpyridine ligands having thiophenol, diaryl disulfide, and alkyl aryl sulfide fragments with Co ii, Ni ii, and Rh iii salts were studied. The structures of the coordination compounds obtained were established based on the elemental analysis data, density functional calculations, and electron spectroscopy. The structure of the complex of 4′-(4-methylsulfanyl)-2,2′:6′,2-terpyridine with Ni(BF4)2 was also established by X-ray diffraction analysis. A method was proposed for the preparation of gold nanoparticle dimeric aggregates via coordination interactions of the ligands adsorbed on the gold nanoparticle surface with transition metal ions. A degree of nanoparticle aggregation upon their reaction with solutions of complex compounds of aurophilic nitrogen-containing ligands was determined by the concentration of the solution of the complex used.

Surface junction effects on the electron conduction of p -phenylene-bridged bis(terpyridine)iron oligomers terminated with a ferrocene moiety were quantitatively analyzed by employing three different surface-anchoring terpyridine ligands. The dependence of the electron-transfer rate constant for oxidation of the ferrocene moiety, k et, on the distance between the electrode surface and the ferrocene moiety, x , showed that the attenuation factor, βd, which indicates the degree of reduction of k et with x , was 0.018 in all cases. However, the absolute k et value depended strongly on both electronic and steric factors of the surface-anchoring ligand.
