Fig. 2. (a) Crystal structure of complex {Ag3(Py[6])(CF3SO3)3(H2O)0.5} (1). Selected bond distances (Å): Ag1–N5 2.154(3); Ag1–N11 2.168(3); Ag2–N9 2.281(4); Ag3–N3 2.284(3). (b) Partial crystal structure of [Ag5S(Py[6])](CF3SO3)3·CH3OH (2). Ag5 and Ag6 each have an occupancy ratio of 0.5. The three triflate groups on the top side of the [Ag5–S] cluster are omitted for clarity. Silver–aromatic π interactions are shown by dashed lines. Ag–C distances (Å): Ag1–C11 2.987; Ag1–C19 2.948; Ag2–C7 2.731; Ag2–C35 2.957; Ag3–C23 2.836; Ag3–C31 3.090. (c) Side view of complex [Ag5S(Py[6])2](CF3SO3)3 (3) with the central silver sulfide cluster represented by a polyhedron. (d) Crystal structure of [Ag12S2(Py[6])2](CF3SO3)8·H2O·CH3OH (4). Two silver atoms each have an occupancy ratio of 0.5. Triflate groups and solvent molecules are omitted for clarity. Color scheme for atoms: Ag, purple; C, gray; H, white; N, blue; S, yellow; F, cyan.
