In the structure of the title compound (systematic name: {(4-chlorophenyl)[2-(2-pyridylmethylidene-κN)hydrazono-κN2]methanolato-κO}dioxovanadium(V)), [VO2(C13H9ClN3O)], the asymmetric unit contains three independent but geometrically similar molecules. The metal centre has a distorted trigonal bipyramidal N2O3 coordination sphere. The planar monoanionic N,N,O-donor ligand occupies one equatorial and two axial positions, the remaining two equatorial positions being occupied by the two oxo groups.

In the title complex, [RuCl2(C7H7NO)(C2H6OS)2], the metal ion is at the centre of a distorted octahedral NOCl2S2 coordination sphere. The neutral 2-acetylpyridine ligand binds to the metal ion through the pyridine N and carbonyl O atoms, forming a five-membered chelate ring. The monodentate S-coordinating dimethyl sulfoxide molecules are mutually cis, and the two remaining positions in the coordination sphere are occupied by two mutually trans Cl− ions.
