The coordination chemistry of multifunctional Schiff base ligands has been the focus of a
considerable number of investigations, because they offer application possibilities in catalysis,
optics, magnetic materials, sensing, separation, etc. [1]. One of the main areas of research
relates to the self-assembly of corresponding metal complexes; gaining an understanding of the
factors that affect such processes remains a challenge. Among the ligand types studied, the
bis(2-hydroxyphenylimine) ligands linked by different spacer units has been of considerable
interest. We have employed a series of such ligands, like the examples H2L1-H2L4, as versatile
building blocks for new supramolecular architectures. In case of Cu(II) monoligand complexes,
double-stranded helicates and metallomacrocycles have been isolated and characterized [2,3].
The different structures will be compared and discussed in detail.
