A hexanuclear gold carbonyl cluster 2015 Access copy available to the general public Unrestricted 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. info:eu-repo/grantAgreement/ES/DGA/E21 info:eu-repo/grantAgreement/ES/MINECO/CTQ2012-35251 info:eu-repo/semantics/openAccess by-nc http://creativecommons.org/licenses/by-nc/3.0/es/ 9.144 2015 CHEMISTRY, MULTIDISCIPLINARY 14 / 163 = 0.086 2015 Q1 T1 4.647 2015 Chemistry (miscellaneous) 2015 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion (orcid)0000-0002-0444-996X Falvello, L.R.
