Notes:
Compounds [(Ph3P)2AgS2CSR (R = But, TIPT(2,4,6-triisopropylthiophenolato))], formed by inserting CS2 into the Ag-S bond in AgSR in the presence of PPh3, react with CH2I2 to give pale yellow crystals of (Ag5I6)n(Ph3PCH2I)n, which consist of the polymeric anion (Ag5I6)n- and the cation (Ph3PCH2)+. The polyanion (Ag5I6)n- is composed of alternate I5-pentagons and Ag5-pentagons that are connected by Ag-I bonds along the C axis to form a layered “pagoda” structure, in which there exists an unusual stereochemistry of iodine. Crystal data: monoclinic, space group P21/c, a = 15.004(12) Å, b = 27.19(2) Å, c = 7.898 Å, β = 97.18(5)°, V = 3205(4) Å3, Z = 4, R = 0.0673 for 2726 observed reflections.
