Abstract Effects of configuration interaction on dielectronic recombination of Cu-like gold ions through the 3d+e → 4l'4l'' capture process are studied in the models of isolated configurations approximation, configuration mixing within 3d94s4l'4l'', and configuration mixing within 3d94l4l'4l'' (l≥0), employing a relativistic distorted-wave approximation. Nonresonant raditive stabilizing transitions and decays to autoionizing levels followed by radiative cascades, as well as resonant stabilizing transitions from the resonant levels, are taken into account. The additional mixing with 3d94l4l'4l'' (0<l≤ l'≤l''3) shifts slightly the peaks of cross section towards low energy. The rate coefficient at low temperature is dramatically changed. The rate coefficient at temperature above 100eV is enhanced by a factor between 26% and 13%.
