• Unsymmetrical tetradentate ligand
• Copper(II) complex
• Molecular structure
• Diethylenetriamine
• Methyl-2-pyrrole carboxylate

A new copper(II) complex with tetradentate unsymmetrical ligand was prepared by one-pot condensation of methyl-2-pyrrole carboxylate, diethylenetriamine and copper(II) sulfate. The complex was characterized by elemental analysis, electronic and IR spectral, as well as X-ray crystal structure determination. The X-ray structure of the molecule reveals the copper(II) center is in a square planar environment through coordination by two nitrogen atoms of the amine, one amide nitrogen atom and one nitrogen atom of the pyrrole moieties, respectively. The copper(II) complex is neutral due to deprotonation of the amide and pyrrole groups.
