Zusammenfassung DieSchiffschen Basen 3-[(2-Benzotrifluorid)-2-hydroxy-3H-naphth-3-yliden)-methyl]-aldamin (1) und 3-[(3-Benzotrifluorid)-2-hydroxy-3H-naphth-3-yliden)-methyl]-aldamin (2) sowie ihre entsprechenden Cu(II)-Komplexe (I,II) wurden synthetisiert und ihre Struktur im Kristall bestimmt. VerbindungI kristallisiert triklin (a=15.561(3),b=16.211(4),c=8.007(2) Å, α=96.29(2), β=101.42(2), γ=97.10(2)°, Raumgruppe $$P_{\bar 1}$$ ,Z=2); VerbindungII kristallisiert monoklin (a=5.064(2),b=19.172(4),c=15.111(3) Å, β=95.05(2)°, Raumgruppe P21/c,Z=2). Aus der Röntgenstrukturanalyse ergibt sich eine quadratisch planare Geometrie der Komplexe.

Summary TheSchiff base ligands 3-[(2-benzotrifluoride)-2-hydroxy-3H-naphth-3-ylidene)-methyl] aldamine (1) and 3-[(3-benzotrifluoride)-2-hydroxy-3H-naphth-3-ylidene)-methyl] aldamine (2) and their corresponding Cu(II) complexes (I, II) were synthesized. The crystal structures ofbis-{(2-benzotrifluoride)-[(2-oxo-3H-naphth-3-ylidene)]-methyl]-aminato} Copper(II) (I) andbis-{(3-benzotrifluoride)-[(2-oxo-3H-naphth-3-ylidene)-methyl]-aminato} Copper(II) (II) were determined. CompoundI crystallizes in the triclinic crystal system (a=12.561(3),b=16.211(4),c=8.007(2) Å, α=96.29(2), β=101.42(2), γ=97.10(2)°, space group $$P_{\bar 1}$$ ,Z=2); compoundII crystallizes in the monoclinic crystal system (a=5.064(2),b=19.172(4),c=15.111(3) Å, β=95.05(2)°, space group P21/c,Z=2). The X-ray diffraction study shows that the geometry around the metal atom is square planar for both copper complexes.
