Abstract
|
|
|
|
A 1D-coordination polymer of 1D-{Cu(μ-picolinato)2}{Hakimi, 2012 #73}n (1), was prepared by the reactions between 2-(2-(pyridin-2-yl)oxazolidin-3-yl)ethanol (AEPC) ligand and CuCl2 or CuBr2. The product was characterized by elemental analysis, UV-Vis, FT-IR spectroscopy and single-crystal X-ray diffraction. The X-ray analysis results revealed that the AEPC ligand, after reactions with the copper(II) chloride or bromide, gives the same product - 1D-{Cu(μ-picolinato)2}n (1). The coordination modes for various picolinate-based ligands were extracted from the Cambridge Structural Database (CSD). In the crystal structure of 1, the copper atom has a CuN2O4 environment and octahedral geometry, which is distorted by elongation of the axial bond lengths due to the Jahn-Teller effect.
