Synthesis of Unstable Carbides Ag2C2n (n=3, 4) and Characterization via Crystallographic Analysis of Their Double Salts with Silver(I) Trifluoroacetate
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 center dot 8AgCF(3)CO(2)center dot 6H(2)O, 4(Ag2C6)center dot 16AgCF(3)CO(2)center dot 14.5DMSO, and 2.5(Ag2C8)center dot 10AgCF(3)CO(2)center dot 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.
