M. Barysz et P. Pyykko, STRONG CHEMICAL-BONDS TO GOLD - HIGH-LEVEL CORRELATED RELATIVISTIC RESULTS FOR DIATOMIC AUBE+, AUC+, AGMG+, AND AUSI+, Chemical physics letters, 285(5-6), 1998, pp. 398-403
Calculations are reported for the singlet ground states of the four, e
xperimentally unknown, title species. Relativistic effects are treated
at the quasirelativistic Douglas-Kroll level. AuBe+, AuSi+ and AuC+ a
re calculated to have at CASPT2 level the largest D-e values known for
gold, 3.636, 3.688 and 3.815 eV, respectively. AuC+ has a short bond,
R-e = 176.6 pm. For AuC+, CCSD(T) reference data are also provided. (
