One-pot synthesis and X-ray studies on cyclic oligobipyridines and one of their dinuclear ruthenium complexes

Abstract

A one-pot synthesis of three new macrocycles containing two, three or four 2,2′-bipyridine units is described; the X-ray analysis of the bis-bipyridine ligand reveals a cyclophane type structure; the X-ray structure of one of the diastereoisomers of the dinuclear ruthenium complex is also described and shows two metal centres held in close proximity.
