Abstract

Pyrazine-2-carboxylic acid reacts with Ni2+ and Fe2+ forming sol. or solid complexes depending on exptl. conditions. The equil. in aq. soln. (1M ClO4-, 25°) were studied by spectrophotometric methods. For both systems only mononuclear species with metal/ligand ratios 1:1, 1:2, and 1:3 were found. The spectrophotometric characteristics and the equil. consts. of the complexes are reported. The solid compds. were analyzed by diffuse reflectance, IR spectrophotometry, and thermal anal.
