resorcinol analogues have been determined by NMR-measurements. The complexing behaviour of bis- and octahydrazones has been studied by liquid–liquid extraction towards the s-metal ions (Li+, Na+, K+, Cs+ and Ca2+), p-metal ions (Pb2+), d-metal ions (Co2+, Ni2+, Cu2+, Zn2+, Cd2+ and Hg2+) and f-metal ions (La3+, Gd3+ and Lu3+). The stoichiometry of complexes and the extraction constants have been determined
