Crystal structure of tetraphenylphosphonium triiododiargentate(I) acetonitrile monosolvate, [(C6H5)4P][Ag2I3] · CH3CN

Abstract

C26H23Ag2I3NP, monoclinic, P121/n1 (no. 14), a = 15.616(2) Å, b = 7.0424(7) Å, c = 26.237(3) Å, Source of materialThe title compound was obtained via an electrolysis by which AgTe was dissolved at the cathode into an electrolyte of (Ph4P)I (99.9 %, Acros) saturated in acetonitrile (> 99.5 %, Merck, dried over 3 Å molecular sieve). Tetrathiafulvalene (TTF, Aldrich) served as anode material. AgTe was prepared by heating a thoroughly ground mixture of 2.2903 g of Ag (powder, 99.9 %,

“…In principle, compounds with chain-like [Ag 2 I 3 ] − anions were already described in the literature. 37 However, a formation of infinite Ag + chains with attractive d 10 –d 10 interaction was only discussed for [C 8 H 9 N 2 ][Ag 2 I 3 ] by Zhang. 38 This compound has a comparable connectivity of AgI 4 tetrahedra as in 6 but only contains iodine and exhibits significantly longer Ag–Ag distances (322.9–334.9 pm) than in 6.…”
