Diversity of aggregation motifs in gold(I) dithiocarboxylate complexes

Author affiliations


Neutral, homoleptic gold(I) dithiocarboxylate complexes with different-sized Me, iPr, Mes, Tip, Mes* and Dmp substituents at the dithiocarboxylate unit were synthesized by reacting the corresponding dithiocarboxylic acid with potassium dicyanoaurate(I). They were characterized by IR spectroscopy and elemental analyses and their structures were determined by single crystal X-ray diffraction. The dinuclear complexes with an intramolecular d10–d10 type aurophilic interaction aggregate through additional intermolecular aurophilic interactions in different binding motifs. The molecular structures and the patterns of aggregation in the solid state are presented and discussed with respect to the influence of the substituent size.
