Understanding Regium Bonds and their Competition with Hydrogen Bonds in Au2:HX Complexes

Abstract: A theoretical study of the regium and hydrogen bonds (RB and HB, respectively) in Au2:HX complexes has been carried out by means of CCSD(T) calculations. The theoretical study shows as overall outcome that in all cases the complexes exhibiting RB are more stable that those with HB. The binding energies for RB complexes range between −24 and −180 kJ ⋅ mol−1, whereas those of the HB complexes are between −6 and −19 kJ ⋅ mol−1. DFT‐SAPT also indicated that HB complexes are governed by electrostatics, but RB compl… Show more

“…Für Au 2 gibt es offensichtlich einen deutlichen Unterschied zwischen diesen berechneten und dem experimentellen Wert von 2.4715 Å (siehe oben). In älteren und jüngeren theoretischen Untersuchungen von Au 2 werden Daten um die 2.50 Å (MP2) und wieder solche am kürzeren Ende (MP2: 2.429 Å) erhalten . Diese Diskrepanz ist momentan noch unerklärt.…”

“…In diesen Untersuchungen werden die Oberflächen von Au n ‐Nanopartikeln analysiert, um Bereiche mit einer Präferenz für Donor‐ und Akzeptor‐Wechselwirkungen mit Substratmolekülen zu lokalisieren . Das zweiatomige Molekül ist der kleinste “Cluster” und es wurde gefunden, dass es elektrophile σ‐Löcher für die Anlagerung von Nukleophilen wie Ammoniak oder Wasser in Verlängerung der Molekülachse anbietet, welche, was den Abstand betrifft, den aktiven Positionen auf einer reinen Goldoberfläche ähnlich sind.…”
