The electrochemical reduction of an unsaturated mixed-metal cluster anion: Synthesis and x-ray crystal structure of [(Ph3P)2N][{Os3H(CO)10}2Ag]

Abstract The unsaturated mixed-metal cluster anion [{Os 3 H(CO) 10 } 2 Ag] − has been prepared by the reaction of [(Ph 3 P) 2 N][Os 3 H(CO) 11 ] with Ag[PF 6 ], and the anion has been shown by an X-ray analysis to consist of an Ag I atom linking together two “Os 3 H(CO) 10 ” fragments. The electrochemistry of this complex has been investigated and it has been shown to undergo two one-electron reductions.
