• A single crystal of polymeric copper (II) complex (1) has been synthesized.
• Crystal structure has been determined by single crystal X-ray diffraction analysis.
• Crystal structure was characterized by IR, thermal analysis, 1H NMR and 13C NMR.
• Magnetic susceptibilities have been measured over the temperature range 2–350 K.
• Magnetic studies have been showed antiferromagnetic interaction between metal ions.
A single crystal of copper (II) complex (1) has been synthesized and its crystal structure has been determined by single crystal X-ray diffraction analysis and characterized by elemental analyses, IR spectroscopy, thermal analysis, 1H NMR and 13C NMR spectroscopy. The complex crystallizes in orthorombic space group Pnma, with unit cell dimensions a = 9.8944, b = 25.2972, c = 7.4457 Å, β = 90°. Structural analysis of (1) shows that the Schiff base ligand coordinates toward one metal atom in a pentadentate mode and each Cu atom is six-coordinated. The aliphatic oxygen atom of Schiff base ligand links the [CuL] moieties and creates polymeric zig-zag chain structure. In addition, magnetic susceptibilities for complex (1) have been measured over the temperature range 2–300 K and the magnetic parameters have been determined with fitting procedure. Magnetic measurements on (1) reveal the presence of antiferromagnetic exchange interactions between Cu(II) ions in the dimeric unit via bridging oxygen atoms of pentadentate Schiff base ligand.
