Abstract
The incorporation of benzene-l,2-dithiolato building blocks into supramolecular coordination assemblies
is the main objective of the investigations described here. Special interest is directed towards dinuclear
complexes with bis(benzene-l,2-dithiolato) ligands, which might be able to form helical structures.
Bis(benzene-l,2-dithiolato) ligands are accessible by ortho-functionalization and subsequent linkage of two
benzene-l,2-dithiol units. The preparation of well defined complexes of titanium, cobalt and nickel with
bis(benzene-l,2-dithiolato) ligands requires strictly thermodynamic equilibration conditions. In that case the
size and shape of the ligand backbone determine if dinuclear double-stranded or mononuclear chelate
complexes are obtained. The dinuclear double-stranded complexes with Ni(II) and Ni(III) are characterized
by a coplanar non-helical arrangement of the square-planar bis(benzene-l,2-dithiolato)nickelate moieties.
