title: Systematic investigation of silver-carbon bonding in coordination frameworks with aryl ligands that contain ethynyl and ethenyl substituents.
abstract: Single-crystal X-ray diffraction of a series of ten crystalline silver(I)-trifluoroacetate complexes that contained designed ligands, each of which was composed of an aromatic system that was functionalized with terminal and internal ethynyl groups and a vinyl substituent, provided detailed information on the influence of ligand disposition and orientation, coordination preferences, and the co-existence of different types of silver(I)-carbon bonding interactions (silver-ethynide, silver-ethynyl, silver-ethenyl, and silver-aromatic) on the construction of coordination networks that were consolidated by argentophilic and weak inter/intramolecular interactions. The complex AgL10⋅6 AgCF3CO2⋅H2O⋅ MeOH (HL10 = 1-{[4-(prop-2-ynyloxy)-3-vinylphenyl]ethynyl}naphthalene) is the first reported example that exhibits all four kinds of silver(I)-carbon bonding interactions in the solid state.
