Abstract
One‐pot reactions of a catechol‐scaffolding aroylbis(N,N‐diethylthiourea) H2Lcat and mixtures of lanthanide nitrates Ln(NO3)3 (Ln3+ = La3+, Nd3+ or Yb3+) or indium(III) chloride InCl3 and [Au(tht)Cl] in methanol in the presence of the supporting base Et3N result in gold(I) {2}‐metallacoronates. Depending on radii of the trivalent metal ions, the corresponding complexes are separated either in the neutral form with the composition {(NO3‐κ2‐O,O’)Ln [[EQUATION]] [Au2(Lcat)2]} in the cases of La3+ and Nd3+ or as the ‘ion‐pair’ {Yb [[EQUATION]] [Au2(Lcat)2]}+(NO3)‐ for the Yb(III) compound. The cationic complexes can be isolated in higher yields as the PF6‐ salts {M [[EQUATION]] [Au2(Lcat)2]}+(PF6)‐ (M3+ = Yb3+ or In3+) by treatment of reaction mixtures with (n‐Bu4N)(PF6).
