ResumoThe displacement of tetrahydrothiophen (tht) in [Au(tht)2]ClO4 by neutral ligands gives bi-, tri- or tetra-coordinated complexes of the type [Au- (py)2]ClO4, [(tht)AuPPh2NHPPh2Au(tht)] (ClO4)2, [LAu(LL)]ClO4 (L=tht, PPh3; LL=bipy, phen) or [AuL4]ClO4 (L=PPh3, AsPh3 or SbPh3). The reaction between [Au(tht)2]ClO4 and (Bu4N)[AuR2] (R=C6F5, C6Cl5, C6F3H2) yields RAu(tht). The 197Au Mössbauer spectrum of [LAu(LL)]ClO4 establishes it as a tri-coordinated species, albeit with an asymmetrically linked bidentate ligand.
