Polyaurated complexes of the dimethylsulfoximide anion [Me2S(0 )N]_ have been prepared by reacting N-trimethylsilyl-dimethylsulfoximide with [(Ph3P)Au]BF4 in various molar ratios. With one or two equivalents of the gold(I) reagent only the dinuclear complex is obtained in high yield: {[(Ph3P)Au]2NS(0 )Me2}+ BF4. With three or four equivalents only the trinuclear complex is produced: {[(Ph3P)Au]...
A series of benzobisimidazolium salts have been prepared and treated with [PtCl2(dppe)] or [PtCl2(dmpe)] in the presence of sodium acetate to yield dinuclear dicarbene-bridged complexes of the type [(P^P)(X)Pt(benzodicarbene)Pt(X)(P^P)](X)2 [5]Br2-[11]I2. The reaction of compounds [7]Br2 and [11]I2 with AgPF6 in acetonitrile led to the exchange of the metal-bound bromo or iodo ligands for aceto...
Silver(I) coordination complexes with the versatile and biomimetic ligands 1,2,4-triazolo[1,5-a]pyrimidine (tp), 5,7-dimethyl-1,2,4-triazolo[1,5-a]pyrimidine (dmtp) and 7-amine-1,2,4-triazolo[1,5-a]pyrimidine (7atp) all feature dinuclear [Ag(2)(μ-tp)(2)](2+) building units (where tp is a triazolopyrimidine derivative), which are the preferred motif, independently of the counter-anion used. Acco...
