In this thesis, gold(I) complexes with triple-bonded ligands - cyanides, isocyanides and acetylides - were studied by preparative, analytical, spectroscopic and structural methods. The solid state structures of the monogold and digold acetylides show significant gold-gold interactions. The aurophilic bonding, together with the sterical effect of the ligands, determines the oligomerization and supramolecular structure of the complexes. In the case of [Au(CN)2]- anions, these aurophilic interactions do not appear, even in a crystal lattice with large [PPN]+ cations, because of electrostatic repulsion of like charges. Quantum-chemical analysis demonstrates a weak Au--Au attraction in isocyanide complexes with large intermolecular Au--Au contacts, even though there is no significant aurophilic interaction in the solid state structure.
