doi:10.1039/c5sc01578bengMartínez-Salvador, S.Falvello, L.R.Martín, A.Menjón, B.A hexanuclear gold carbonyl clusterART-2015-92037The 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.2015http://zaguan.unizar.es/record/5836610.1039/c5sc01578bhttp://zaguan.unizar.es/record/58366oai:zaguan.unizar.es:58366info:eu-repo/grantAgreement/ES/DGA/E21info:eu-repo/grantAgreement/ES/MINECO/CTQ2012-35251Chemical Science 6, 10 (2015), 5506-5510by-nchttp://creativecommons.org/licenses/by-nc/3.0/es/info:eu-repo/semantics/openAccess
