A hexanuclear gold carbonyl cluster
Martínez-Salvador, S. ; Falvello, L.R. (Universidad de Zaragoza) ; Martín, A. (Universidad de Zaragoza) ; Menjón, B.
Resumen: The hexanuclear gold carbonyl cluster [PPh4]2[Au6(CF3)6Br2(CO)2] (4) has been obtained by spontaneous self-assembly of the following independent units: CF3AuCO (1) and [PPh4][Br(AuCF3)2] (3). The cyclo-Au6 aggregate 4, in which the components are held together by unassisted, fairly strong aurophilic interactions (Au¿Au ~310 pm), exhibits a cyclohexane-like arrangement with chair conformation. These aurophilic interactions also result in significant ¿(CO) lowering: from 2194 cm-1 in the separate component 1 to 2171 cm-1 in the mixed aggregate 4. Procedures to prepare the single-bridged dinuclear component 3 as well as the mononuclear derivative [PPh4][CF3AuBr] (2) are also reported.
