There has been made the study of complex formation of paraaminosalicylic acid with Cu(II). On the basis of IR spectroscopic and derivatographic methods of analysis the formation of dimer complex containing Cu–Cu bond with chemical formulae {Cu₂[p-NH₂C₆H₃(OH)(COO)₂]} is determined. At the interaction of this complex with acetic acid the change of paraaminosalicylic anion on the acetic one takes place, i.e. the complex [Cu₂(CH₃COO)₄(H₂O)₂] is formed.

Keywords : paraaminosalicylic acid, copper(II) sulphate, acetic acid, complex formation
