The diruthenium(I) complex cis- 1 was prepared by reaction of 2-benzylamino-7-methyl-1,8-naphthyridine (Hbmnapy) with in benzene.The N1,N2 co-ordination mode of the bridging ligands is supplemented by N8 as an axial donor atom.In contrast, the analogous reaction with 7-methyl-1,8-naphthyridin-2-one (Hmonapy) or the corresponding 5-methyl-7-phenyl derivative (Hmopnapy) afforded the respective trinuclear clusters cis- 2 and cis- 3, which exhibit three-atom chains with 46 valence electrons.X-Ray structural analyses demonstrate that the Ru-Ru bond distance remains effectively unchanged on going from the Ru2 unit in 1 to the Ru3 sequence in 3 , for which an Ru-Ru-Ru angle of 168.6(3) deg is observed.
