description

The reaction of 2,4,6-tris(pyridyl)-1,3,5-triazine (ptz) and copper(II) salts in DMF–water (4:1) resulted in the hydrolysis of ptz, giving rise to the bis(2-pyridylcarbonyl)amide anion ( ptO 2 - ) and affording the complexes [Cu(ptO 2 )(2-Clbenz)(H 2 O)] ( 1 ), [Cu(ptO 2 )(3-Clbenz)] ( 2 ), and [Cu(ptO 2 )(4-Clbenz)(DMF)] ( 3 ). This report includes the chemical and spectroscopic characterization of all these compounds along with the crystal structures of the Cu(II) complexes thus formed. The coordination spheres of Cu(II) in 1 and 3 are best described as distorted square based pyramidal, while for 2 the coordination sphere is distorted square planar.
