New one-dimensional copper(I) coordination polymer [Cu-2(mu-I)(2)(mu-(thio)(2)dapte)](n) (1) {(thio)(2)dapte = N,N'-di-(thiophenecarbaldehyde)-1,2-di(o-aminophenylthio) ethane} involving a novel (NS)(2) Schiff-base with a flexible spacer has been synthesized and structurally characterized by X-ray diffraction analysis. Each Cu(I) center adopts a distorted [CuN2S2] tetrahedron environment arising from two crystallographically equivalent (thio)(2)dapte Schiff-base ligands. Each ligand acts as N2S2-bis-chelating ligand with the nitrogen atoms of the two imine functions and from the two thioether atoms in anti-form leading to the dinuclear [Cu-2(mu-(thio)(2)dapte)] groups. Such [Cu-2] entities are bridged by two iodine anions [(mu-I)(2)] to form a neutral one-dimensional copper(I) coordination polymer (1). (C) 2008 Elsevier B.V. All rights reserved.
