GOLD(I) COMPLEXES OF AZOLES

(Dimethyl sulphide)AuCl reacts with azoles to give adducts [LAuX](2) [ L = N-methylimidazole (N-MeIm), N-ethylimidazole (N-EtIm), N-propylimi dazole (N-PrIm), 2-methylbenzoxazole (2-MeBO) and 2,5-dimethylbenzoxaz ole (2,5-diMeBO); X = Cl or Br] which were characterized analytically and spectroscopically, including H-1-n.m.r. I.r. and Raman studies sho wed that the compounds were binuclear with bridging halogen atoms. A n itrogen-containing ligand was coordinated to nitrogen N(3) atom of the azole ring in monodentate fashion.
