(a) Coordination environment of the AgI atoms and ethynide groups in (II). Symmetry codes: (A) [-x + {3\over 2}, -y + {3\over 2}, -z + 1]; (B) [-x + 1, y, -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 layer structure in (II), showing notable C-H...F contacts (Table 2[link]).  [article HTML]
