Formation and X‐ray structure of a silver iodide based polymeric complex (Ag5l6)n(Ph3PCH2l)n

Formation and X‐ray structure of a silver iodide based polymeric complex (Ag5l6)n(Ph3PCH2l)n 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.

Abstract

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.
