The preparation and X-ray crystal structures of (CyNC)(AuCN)-C-I, (n-BuNC)(AuCN)-C-I, and (i-PrNC)Au(I)CN(.)0.5CH(2)Cl(2) are reported and compared with those of (MeNC)(AuCN)-C-I and (t-BuNC)(AuCN)-C-I, which were previously described. These linear molecules are all organized through aurophilic interactions into three structural classes: simple chains ((CyNC)(AuCN)-C-I and (t-BuNC)(AuCN)-C-I), side-by-side chains in which two strands make (AuAu)-Au-... contact with each other ((eta-BuNC)(AuCN)-C-I), and nets in which multiple aurophilic interactions produce layers of gold(I) centers ((i-PrNC)(AuCN)-C-I and (MeNC)(AuCN)-C-I). All of these five solids dissolve to produce colorless, nonluminescent solutions with similar UV/vis spectra. However, each of the solids displays a unique luminescence with emission maxima occurring in the range 371-430 nm.
