(a) Coordination environment of the AgI atoms and ethynide groups in (III). Symmetry code: (A) [x + {1\over 2}, -y + {1\over 2}, z + {1\over 2}]. The argentophilic Ag...Ag distances, shown as thick purple rods, lie in the range 2.70-3.40 Å. Ag atoms are drawn with displacement ellipsoids at 50% probability. H atoms and trifluoroacetate ligands are omitted for clarity. (b) Perspective view of the supramolecular network structure in (III), showing notable C-H...F contacts (Table 2[link]).  [article HTML]
