Novel Layered Structures Formed by Iodocuprate Clusters Stabilized by Dialkylsulphide Ligands

Abstract

From solutions of copper iodide and dodecyldimethylsulphonium iodide in acetonitrile, single crystals of [Cu4I4(DodecylMeS)4] (1) and [Cu3I4(DodecylMeS)3](DodecylMe2S) (2) could be obtained. Both compounds crystallize in the triclinic crystal system, space group P1¯ (1: a = 957.23(1), b = 967.25(2), c = 3818.38(6) pm, α = 90.3837(6)°, β = 86.4687(7)°, γ = 75.0996(7)°, 2: a = 874.23(1), b = 979.29(1), c = 4388.75(4) pm, α = 90.4472(3)°, ß = 94.7088(3)°, γ = 116.1162(3)°). 1 consists of tetrahedral Cu4 clusters, which are capped by four iodide ions over the tetrahedral faces. 2 contains trigonal Cu3 clusters, which are coordinated by four iodide ions, one centered over the plane, three bridging over the edges of the Cu3 triangle. In both compounds, the S atoms of (DodecylMeS) ligands coordinate to the Cu atoms. In 2, a (DodecylMe2S) cation is also present.

Luminescent Coordination Polymers Built Upon Cu4X4 (X=Br,I) Clusters and Mono‐ and Dithioethers

“…[(DodecylSMe) 4 {Cu 4 (m 3 -I) 4 }], obtained from treatment of copper iodide with dodecyldimethylsulfonium iodide in acetonitrile, is reported to be monomeric with Cu-Cu distances in the range 266.9-284.6 pm at 299 K. [38] With the objective to study the impact of the substitution pattern of a series of bis(cyclohexylthiomethyl)benzene ligands on the network topologies, the Kim's group synthesized the 1,2-(L1), 1,3-(L2), and 1,4-bis(cyclohexylthiomethyl)benzene (L3) isomers and reacted them with CuI in MeCN solution according Scheme 7.…”

Structure, Dynamics, and Photophysics in the Copper(I) Iodide–Tetrahydrothiophene System

“…The structural chemistry of CuI-sulfide complexes encompasses three major classes, as shown in Scheme 1. A molecular cubane tetramer Cu4I4 with monodentate sulfide ligands has been reported, 5 as have numerous molecular Cu2I2 dimers 4,6 and a single CuI stair step polymer 7 containing chelating disulfide ligands. Far more common are structures in which bridging disulfide ligands link the rhomboid dimers, cubane tetramers, or stair step chains into network arrangements.…”
