The geometries of the whole series of [AuX3]- complexes (X=F, Cl, Br, I) have been calculated by DFT methods. It has also been found that the neutral AuX2 molecules behave as unsaturated species, showing significant affinity for an additional X- ligand. Moreover, in the open-shell [AuX3]- anions, homolytic splitting of one of the Au-X bonds and formation of the lower-valent [AuX2]- anions is favored over non-reducing halide dissociation. They should therefore be prone to disproportionation.2018http://zaguan.unizar.es/record/7828810.1002/chem.201705509http://zaguan.unizar.es/record/78288oai:zaguan.unizar.es:78288info:eu-repo/grantAgreement/ES/DGA/E21info:eu-repo/grantAgreement/ES/MEC/FPU15-03940info:eu-repo/grantAgreement/ES/MINECO-FEDER/CTQ2015-67461-PChemistry - A European Journal 24, 7 (2018), 1514-1517All rights reservedhttp://www.europeana.eu/rights/rr-f/info:eu-repo/semantics/openAccess
