Abstract
The asymmetric unit of the title compound, [RuCl2(C13H9N3)(CO)2], consists of four crystallographically independent RuII complexes. Each RuII atom is in a distorted octahedral environment coordinated by two carbonyl ligands, two Cl atoms and a chelating 2-(2-pyridyl)-1,8-naphthyridine (pynp) ligand. The carbonyl ligands are cis to each other, while the Cl atoms are trans. Relatively short interatomic distances (2.60–2.67 Å) between the uncoordinated N atom of pynp and the C atom of the carbonyl imply a donor–acceptor interaction between the pynp and carbonyl ligands.
