Abstract
The structures of AuH and AuI are already known, now the long-sought-after molecules AuH3 (=(H2)AuH) and AuH5 (=H3Au(H2)) have been detected by matrix isolation spectroscopy. Based on new calculations, the global minimum for AuI3, a missing member of the gold halides, has been elucidated to be that of an L-shaped moiety (Cs symmetry; charge transfer from the I2 unit to the AuI).
