Abstract	The new $[\{Co_{5}C(CO)_{12}\}Au\{Co(CO)_{4}\}]^{−},$ $[1]^{−},$ cluster has been obtained from the reaction of $[Co_{6}C(CO)_{15}]^{2−}$ with two equivalents of $[AuCl_{4}]^{−}.$ $[1]^{−}$ reacts with an excess of $HBF_{4}$ resulting in the formation of $[\{Co_{5}C(CO)_{12}\}_{2}Au]^{−},$ $[2]^{−}.$ The new derivatives $[Co_{5}C(CO)_{12}(AuPPh_{3})],$ 3, and $[Co_{5}C(CO)_{11}(AuPPh_{3})_{3}],$ 4, have been obtained by reacting $[2]^{−}$ with two and four equivalents of $[Au(PPh_{3})Cl],$ respectively. All the new species have been structurally characterised by means of X-ray crystallography as their $[NEt_{4}][1],$ $[NEt_{4}][2],$ $[NMe_{3}(CH_{2}Ph)][2],$ 3 and $4·thf·0.5C_{6}H_{14}$ salts and solvates. $[2]^{−}$ may be viewed as a homoleptic Au(I) complex containing two $[Co_{5}C(CO)_{12}]^{−}$ clusters as ligands. Similarly, $[1]^{−}$ and 3 are heteroleptic Au(I) complexes containing one $[Co_{5}C(CO)_{12}]^{−}$ cluster ligand as well as $[Co(CO)_{4}]^{−}$ or $PPh_{3}.$ Conversely, 4 contains the $[Co_{5}C(CO)_{11}]^{3−}$ cluster stabilized by three $[AuPPh_{3}]^{+}$ fragments. $[1]^{−}$ and $[2]^{−}$ have been investigated in solution by means of electrochemical and spectroelectrochemical methods, revealing a very rich redox propensity to form the closely related $[1]^{n−}$ (n = 1–3) and $[2]^{n−}$ (n = 0–3) species.
