    Notes: Abstract Literature data for vapor-liquid equilibria, activity coefficients at infinite dilution and enthalpies of mixing of 1-chloroalkanes or α,ω-dichloroalkanes + alkyl alkanoates were examined on the basis of the DISQUAC group-contribution model. The interaction parameters for the COO/CI contacts are reported. The quasi-chemical parameters of 1-chloroalkane or long chain α,ω-dichloroalkanes are zero but become increasingly negative for short chain α,ω-dichloroalkanes. The model provides a fairly consistent description of the experiment data. The properties of many other systems can be predicted using the same set of parameters.

    Description / Table of Contents: Zusammenfassung Es wurden die Schiffbasen-Liganden 3-[(Phenyl)-2-hydroxy-3H-naphth-3-yliden)-methyl]aldamin (1) und 3-[(Benzen-4-trifluoromethyl)-2-hydroxy-3H-naphth-3-yliden)-methyl]aldamin (2) inklusive der entsprechenden Kupfer(II)-KomplexeI undII dargestellt. VonI undII wurden die Kristallstrukturen ermittelt. KomplexI kristallisiert im triklinen System mita=10.804(5),b=12.589(5),c=10.369(3) Å, α=107.72(3), β=95.75(3) und γ=76.32(4)° in der Raumgruppe P $$\bar 1$$ mitZ=2. VerbindungII kristallisiert ebenfalls im triklinen System mita=10.718(2),b=13.861(4),c=10.110(9) Å, α=95.99(2), β=90.16(2) und γ=93.90(2)° in der Raumgruppe P $$\bar 1$$ mitZ=2. Die Geometrie rund um Cu ist in beiden Komplexen quadratisch-planar.
    Notes: Summary The Schiff base ligands, 3-[(Phenyl)-2-hydroxy-3H-Naphth-3-ylidene)methyl]aldamine (1) and 3-[(benzene-4-trifluoromethyl)-2-hydroxy-3H-naphth-3-ylidene)methyl]aldamine (2), and their corresponding Cu(II) complexes (I andII were synthesized. The crystal and molecular structures ofI andII were determined. CompoundI crystallizes in the triclinic crystal systema=10.804(5),b=12.589(5), andc=10.369(3) (Å), α=107.72(3), β=95.75(3), and γ=76.32(4)(°), in the space group P $$\bar 1$$ withZ=2. CompoundII crystallizes in the triclinic crystal systema=10.718(2),b=13.861(4), andc=10.110(9) (Å), α=95.99(2), β=90.16(2), and γ=93.90(2)(°), in the space group P $$\bar 1$$ withZ=2. The geometry around the metal atom in both complexesI andII is square planar.
