By decarbonylated substitution reactions, rod-like ruthenium complexes of 1,2-naphthoquinone-1-oxime (1-nqo) are synthesized as trans-,cis- and cis-, cis-[Ru(1-nqo) 2(CO)(spy)] (3) and (4) which containing C 16 long alkyl chains in the molecules, cis-,cis-[Ru(1-nqo) 2(CO)(opy)] (5) and trans-,trans-[Ru(1-nqo) 2(opy) 2] (6) which containing C 18 long alkyl chains in the molecules. The complexes are characterized by IR, FAB MS, 1H- 1H COSY NMR and UV-visible spectra.
