Neutral LAuICl (L= CO, RNC) organometallic complexes that exhibit crystal structures with molecules packing in extended structures have comparable luminescence properties, showing orange-red unstructured phosphorescence bands and extremely large Stokes shifts (15-20× 103 cm-1) in the solid state. The long aurophilic distances in the ground state (3.2-3.6 Å) are computed to contract in the phosphorescent excited state (~ 2.6 Å) due to ...
