Addition of a bidentate ligand (L-L=1,10-phenantroline, o-phenylenebis(dimethylarsine) to solutions of Au(C6F5)X2(tht) (X=Cl, Br; tht=tetrahydrothiophene) leads to potentially five-coordinate gold(III) derivatives. 197Au Moesbauer spectroscopy points, however, to four-coordinate square-planar complexes with a weak penta-coordination in the phen-containing derivatives.The complexes react with AgClO4 to give four-coordinate cationic complexes of the types ClO4 or (ClO4)2.
