synthesis of complicated heterolepticligands based on pyridine and 1H-benzimidazole moieties. The key-step formation of aromatic 1H-benzimidazole rings from N-(2-nitroaryl)arenecarboxamides significantly improves the possibilities of the classical intermolecular Phillips reactions and can be applied to the synthesis of large oligo-multidentate units. Segmentalheterolepticligands containing two different
