Copper Halide Adducts of Copper Schiff Base Complexes
Structure and magnetic properties
The complete crystal and molecular structures of four complexes, dichlorobis (N-methylsalicylaldimino)dicopper(II), dichlorobis (N-ethylsalicylaldimino)dicopper(II), dibromobis (N-ethylsalicylaldimino)dicopper(II), and dichloro[N,N′ ethylenebis(2-hydroxyacetophenimino)copper(II)]copper(II) have been determined by X-ray diffraction analyses. The magnetic moments of the complexes are dependent on temperature but not pressure, indicating the absence of any significant volume changes, in agreement with the X-ray data. The magnetic properties are found to be more a function of structure than of the electronic properties of the ligands. In each case, increased distortion of the copper environment from planar is accompanied by reduced antiferromagnetic interaction between the pairs of copper atoms. Replacement of chlorine atoms attached directly to the interacting copper atoms has no significant effect on the magnetic properties in dichlorobis-(N-ethylsalicylaldimino)dicopper(II). Using these results and the magnetic properties, the copper environments may now be deduced in a series of analogous binuclear copper complexes.
