C. Kaes et al., ONE-POT SYNTHESIS AND X-RAY STUDIES ON CYCLIC OLIGOBIPYRIDINES AND ONE OF THEIR DINUCLEAR RUTHENIUM COMPLEXES, Journal of the Chemical Society, Chemical Communications, (14), 1995, pp. 1445-1446
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 stru
cture of one of the diastereoisomers of the dinuclear ruthenium comple
x is also described and shows two metal centres held in close proximit
