## Abstract The reaction of 2,4,6‐tri(pyridyl)‐1,3,5‐triazine (ptz) and copper(II) salts in dmf/water (1:1) results in the hydrolysis of ptz and formation of the anions bis(2‐pyridylcarbonyl)amide (ptO~2~^–^) and bis(2‐pyridylamine)amide (ptN~2~^–^), which are found in the complexes [Cu(ptN~2~)(OAc
