New (NS)2 Schiff base with a flexible spacer: Synthesis and structural characterization of its first coordination polymer [Cu2(μ-I)2(μ-(thio)2dapte)]n (1)

Abstract : New one-dimensional copper(I) coordination polymer [Cu2(μ-I)2(μ-(thio)2dapte)]n (1) {(thio)2dapte = 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)2dapte 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 [Cu2(μ-(thio)2dapte)] groups. Such [Cu2] entities are bridged by two iodine anions [(μ-I)2] to form a neutral one-dimensional copper(I) coordination polymer (1).
