The structure of [Ph4As]2[Re7C(CO)21Au(PPh3)] has been determined by X-ray crystallography. The mixed-metalclusteranion adopts a 1,4- (i.e. trans-) bicapped octahedral geometry. Solution 13C NMR spectra reveal that this Au(PPh3)+ adduct of [Re7C(CO)21]3− maintains the (1,4)-bicapped structure in solution whereas the corresponding H+ adduct, [HRe7C(CO)21]2−, displays two isomers.
