The asymmetric unit of the title compound, [RuCl(2)(C(13)H(9)N(3))(CO)(2)], consists of four crystallographically independent Ru(II) complexes. Each Ru(II) atom is in a distorted octa-hedral environment coordinated by two carbonyl ligands, two Cl atoms and a chelating 2-(2-pyrid-yl)-1,8-naphthyridine (pynp) ligand. The carbonyl ligands are cis to each other, while the Cl atoms are trans. Relatively short inter-atomic distances (2.60-2.67 Å) between the uncoordinated N atom of pynp and the C atom of the carbonyl imply a donor-acceptor inter-action between the pynp and carbonyl ligands.
