Abstract :
The product obtained from the reaction of pyridine-2,3-dicarboxylic acid and hydrated copper(II) chloride in hot aqueous NaOH solution was determined by low temperature X-ray diffraction to be [Cu3(C6H4NO3)4(OH)2(H2O)2]n or [Cu3(μ-OH)2(μ-nicNO)4(H2O)2]n (nicNO is pyridine-3-carboxylate N-oxide), a structure obtained from room temperature data and reported previously. The present determination is improved in quality and treatment of the H atoms. A Hirshfeld surface analysis of the intermolecular interactions is presented.
