Abstract

Two new silver(I) carbides, Ag2C6 and Ag2C8, have been synthesized, and single-crystal X-ray analysis of their crystalline silver(I) trifluoroacetate complexes, Ag2C6·8AgCF3CO2·6H2O, 4(Ag2C6)·16AgCF3CO2·14.5DMSO, and 2.5(Ag2C8)·10AgCF3CO2·10DMSO, provides detailed information on the influence of ligand disposition and orientation of the all-carbon anionic ligands in the construction of multidimensional supramolecular structures, which are consolidated by argentophilic and weak inter-/intramolecular interactions.
