Synthesis and crystal structure of a one-dimensional copper(I) polymer containing a bis-bidentate tetrathioether ligand

Abstract

Acompound, [(CuI) 2(TPTB)] n (TPTB= 1,2,4,5-tetra-isopropyl-thiobenzene) has been synthesized and characterized. The complex crystallizes in the monoclinic space group P2 1 with a = 8.709(3) å, b = 18.056(2) å, c= 8.755(2) å, β = 96.16(2) ∘, V = 1368.7 (5) å 3 and Z = 2. The complex contains one-dimensional infinite chain structure consisting of copper(I) ions, bridging bis-bidentate tetrathioether ligands and bridging iodide ions. The chains are connected by S•••S contacts of the ligands, resulting in the formation of a two-dimensional network. The iodide-doping for the colorless powder sumple give rise to the enhancement the conductivity (5.6 X 10 −6 Scm −1).
