[Cu2(μ-Me2N-ba)2bn)I]_n,1D coordination polymer of copper(I) iodide: synthesis, characterization, and crystal structure

摘要

A new one-dimensional coordination polymer of copper(I) iodide [Cu((μ_(N,N')-Me2N-ba)2bn)I]_n, with the bidentate Schiff-base ligand N,N'-bis(4-dimethylamino-benzylidene)butane-1,4-diamine, (Me2N-ba)2bn, containing a flexible spacer (=N-C-C-C-C-N=) has been synthesized and characterized by elemental analyses, ~(13)C and ~1H NMR, FT-IR, and thermal analysis. Its molecular structure has been determined by single-crystal X-ray diffraction. The cop-per(I) ion is coordinated in a distorted trigonal planar geometry by two N atoms of the symmetry related Schiff-base ligands and one I atom. The Schiff-base ligand adopts an E,E conformation and acts as a bis-monodentate bridging ligand (μ_(N,N'), thus forming the 1D-chain copper(I) iodide coordination polymer.
