Struktur von Bis(3-phenyl-4-benzoyl-isoxazol-5-onato)kupfer(II)/Structure of Bis(3-phenyl-4-benzoyl-isoxazol-5-onato)copper(II)

The crystal structure of bis(3-phenyl-4-benzoyl-isoxazol-5-onato)copper(II) was determined for com parison with the copper complexes of 1-ghenyl-3-methyl-4-benzoyl-pyrazol-5-one and some β-diketones. Crystal data: a = 13,320(6) Å; b = 8,421(7) Å; c = 11,516(4) Å; β = 92,34(4)°; space group P21/c ; Z = 2; R = 0,041; 2088 unique reflexions.

Komplexbildung und Metallextraktion mit heterocyclischen β-Dicarbonylverbindungen im Vergleich. Struktur von 3-Phenyl-4-benzoyl-isoxazol-5-on / Complex Formation and Metal Extraction with Heterocyclic β-Dicarbonyl Compounds as Comparison. Structure of 3-Phenyl-4-benzoyl-5-isoxazolone

Acid constants and stability constants of nickel and zinc chelates with 2-thenoyltrifluoroacetone, dibenzoylmethane, 1-phenyl-3-methyl-4-benzoyl-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 determined by X-ray analysis. Crystal data: a = 874,7(2), b = 1959,2(7), c = 897,38(7) pm; β = 101,030(7)°; space group P 121/c 1; Z = 4; R = 0,043; 1920 observed, unique reflexions.
