Abstract
The product obtained from the reaction of pyridine-2,3-di-carb-oxy-lic acid and hydrated copper(II) chloride in hot aqueous NaOH solution was determined by low temperature X-ray diffraction to be [Cu(3)(C(6)H(4)NO(3))(4)(OH)(2)(H(2)O)(2)] (n) or [Cu(3)(μ-OH)(2)(μ-nicNO)(4)(H(2)O)(2)] (n) (nicNO is pyridine-3-carboxyl-ate 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 inter-molecular inter-actions is presented.
