Abstract
Composition of coordination compounds formed by copper(II) or zinc(II) ions and pyridine-2-, -3-, and -4-carbohydrazones of pyridoxal-5-phosphate in aqueous solution at 298.2 K, рН 7.4, I 0.25 has been studied by means of spectrophotometry. Conditional constants of the complexes stability have been determined. Cu(II) ions formed more stable ML2 coordination compounds in comparison with Zn(II), zinc(II) ions are efficiently bound to the derivative of picolinic acid hydrazide to form the ML complex.
