Gold-isocyanide complexes XAu(RNC) (X = halide, pseudohalide, R = alkyl, aryl) and water soluble gold-carbene complexes XAuC(NHPh)[MeN(CH 2CH2O)nMe] (X = Cl, n = 1-11) have been prepared and evaluated as substrates for the direct laser writing of gold decoration onto ceramics.

The preparation of three isonitrile complexes (CyNC)AuICl, (CyNC)AuIBr and (CyNC)AuIl, along with their structural and spectral characterization, are reported. X-ray crystal structures reveal that these crystallize in the same space group and have closely related structures. The structures involve pleated chains of linear, two-coordinate monomers that are arranged in a head-tail fashion. However, these chains vary significantly in the degree of aurophilic interactions among the individual molecules. Thus, (CyNC)AuICl forms infinite chains with alternating Au...Au distances of 3.3894(7) and 3.5816(7) A. Within the chains of (CyNC)AuIBr, however, the alternation of Au...Au distances is more pronounced so that there are dimers, with an Au...Au distance of 3.4864(9) A, and neighboring gold centers at 3.7036(9) A. In (CyNC)Au Il, the gold-gold contacts do not lie within the range of significant aurophilic bonding. The closest Au...Au distance is 3.7182(11) A while every other Au...Au distance is 3.9304(12) A. The steric factor of the X ligand and dipole-dipole interactions between the antiparallel complexes is much more significant than aurophilic interactions in governing the self-association of the complexes in this series. The colorless crystals of each solid display an orange luminescence band with a strikingly large Stokes' shift (～21 000 cm-1, 2.6 eV). However, considerable care had to be taken to ensure that the crystals used for the study of the luminescence were free of a surface impurity that produced a turquoise-green luminescence in (CyNC)AuICl. The diffuse reflectance spectra for the solids show a similar three-band pattern in the 200-330 nm range.
