In the title compound, [RuCl(2)(C(6)H(16)N(2))(CO)(2)], the geometry around the Ru(II) atom is a distorted RuC(2)N(2)Cl(2) octa-hedron, with pairs of C and Cl atoms trans to each other and the N atoms of the bidentate ligand in a cis conformation. The five-membered chelate ring is puckered on the C-C bond.
