Abstract
The design, synthesis, and characterization of the 10 linear and bent acentric ligands 1–10 (tectons) based on the differentiation of two divergently disposed coordinating poles is reported. The nature of the two poles and their distance are varied by the use of different linear spacers. For these molecules, a monodentate coordinating site, i.e., a pyridine ring, and a tridentate coordinating site, i.e., a pyridine moiety bearing at the 2 and 6 positions either two thioether groups or two dimethylamino units (PySMe and PyN(Me~2~)~2~ type, resp.), a terpyridine, or a pyridine ring bearing two optically pure dihydrooxazole units, are combined.
