Abstract
Acid constants and stability constants of nickel and zinc chelates wit h 2-thenoyltrifluoroacetone, dibenzoylmethane, 1-phenyl-3-methyl-4-ben zoyl-5-pyrazolone and 3-phenyl-4-benzoyl-5-isoxazolone were compared. The extraction of copper was studied. Thermoanalytic measurements were made using the ligands and their copper compounds in the solid state. The molecular structure of 3-phenyl-4-benzoyl-5-isoxazolone was deter mined by X-ray analysis. Crystal data: a = 874,7(2), b = 1959,2(7), c = 897,38(7) pm; beta = 101,030(7)degrees: space group P12(1)/c1; Z = 4 ; R = 0,043; 1990 observed, unique reflexions.
