The complex originates as a consequence of an intramolecular addition of the AuCCTol fragment to the internal diphosphine triple bond Ph2PCCPPh2. The crystal structure of the tetranuclear complex shows a dinuclear metallacycle with a very short Au¿Au bond interaction and bridging phosphino-enyne ligands. This disposition clearly stabilises the elusive vinyl gold species omnipresent as intermediates in gold-catalysed reactions.2017http://zaguan.unizar.es/record/16933310.1039/c7cc03713ahttp://zaguan.unizar.es/record/169333oai:zaguan.unizar.es:169333Chemical Communications 53, 66 (2017), 9202-9205All rights reservedhttp://www.europeana.eu/rights/rr-f/info:eu-repo/semantics/closedAccess
