Crystal structures and spectroscopic properties of copper(II)-bis(2-pyridylcarbonyl)amide-chlorobenzoate complexes

The reaction of 2,4,6-tris(pyridyl)-1,3,5-triazine (ptz) and copper(II) salts in DMF-water resulted in the hydrolysis of ptz, giving rise to the bis(2-pyridylcarbonyl)amide anion (ptO2-) and affording the complexes [Cu(ptO2)(2-Clbenz)(H2O)], [Cu(ptO2)(3-Clbenz)], and [Cu(ptO2)(4-Clbenz)(DMF)]. This report includes the chemical, the spectroscopic characterization and the crystal structures of all these compounds.
