Three novel cyclooctadiazabiaryl ligands, namely cycloocta[2,1-b:3,4-b′]dipyridine (3), cycloocta[2,1 -b:3,4-b′]diquinoline (4) and cycloocta[2,1-b:3,4-b′]di[1,8]naphthyridine (5) have been synthesized and a number of metal complexes have been prepared for these novel ligands. The energy barrier to ring inversion of these compounds have also been studied.
