摘要:
A series of eight silver(I) trifluoroacetate complexes based on aromatic ligands bearing terminal ethynyl and ethenyl groups on separate pendent arms has been synthesized. Single-crystal X-ray analysis of the complexes provided detailed information on the influence of argentophilicity, ligand disposition and orientation, and the co-existence of three types of silver-carbon bonding (silver-ethynide, silver-ethenyl and silver-aromatic) in coordination network construction, as well as the roles played by weak pi-pi stacking and anion-pi interactions in supramolecular assembly.
