Mechanical properties of one-dimensional coordination polymer [Cu(adi)(4-pyao)2]n

Abstract

Blue block crystals of title compound, [Cu(adi)(4-pyao)2]n 1 were obtained by blending the solution of copper (II) fluoride with 4-pyridine-aldoxime (4-pyao) and adipic acid (H2adi). X-ray single crystal structure analysis revealed that 1 crystallizes in the triclinic space group P-1 (No 2). The metal N2O2-square-planar geometry is completed by two N-pyridine and two carboxylic oxygen atoms. The adipate dianions act in the bis-monodentate coordination mode and bridge the copper cations giving rise to 1D polymeric chain, while the 4-pyao ligands co-ordinate via pyridine nitrogen atoms (Figure, left). The Cu•••Cu separation across the carboxylic group in the polymeric tapes is equal to 9.692 Å.
