Abstract
Single-crystal X-ray analysis of a series of six silver(I) trifluoroacetate complexes containing designed ligands each composed of a functionalized cis- or trans-stilbene skeleton bearing two terminal ethynyl groups at variable ring positions provided detailed information on the influence of ligand disposition and orientation, coordination preferences, and coexistence of different types of silver(I)–carbon bonding (silver–ethynide, silver–ethenyl and silver–aromatic) in the construction of a coordination network, which are consolidated by argentophilic and weak intra/intermolecular interactions. The complex 3(Ag2L6)·14AgCF3CO2·[Ag2(CH3CN)3](CF3CO2)2·4H2O·6CH3CN [H2L6 = (E)-1,2-bis(4-ethynylphenyl)ethene] is the first reported example in which an ethynide terminal is bound by six silver(I) ions.
