- Abstract
The synthesis, X-ray crystal structures, electrochemical, and spectroscopic studies of a series of hexanuclear gold(I) μ3-ferrocenylmethylphosphido complexes stabilized by bridging phosphine ligands, [Au6(PP) n(Fc-CH2-P)2][PF6]2 ( n=3, PP=dppm (bis(diphenylphosphino)methane) ( 1), dppe (1,2-bis(diphenylphosphino)ethane) ( 2), dppp (1,3-bis(diphenylphosphino)propane) ( 3), Ph2PN(C3H7)-PPh2 ( 4), Ph2PN(Ph-CH3- p)PPh2 ( 5), dppf (1,1′-bis(diphenylphosphino)ferrocene) ( 6); n=2, PP=dpepp (bis(2-diphenylphosphinoethyl)phenylphosphine) ( 7)), as platforms for multiple redox-active ferrocenyl units, are reported. The investigation of the structural changes of the clusters has been probed by introducing different bridging phosphine ligands. This class of gold(I) μ3-ferrocenylmethylphosphido complexes has been found to exhibit one reversible oxidation couple, suggestive of the absence of electronic communication between the ferrocene units through the Au6P2 cluster core, providing an understanding of the electronic properties of the hexanuclear AuI cluster linkage. The present complexes also serve as an ideal system for the design of multi-electron reservoir and molecular battery systems.
