The hemerythrin-type dinuclear title complex, [Ru2(CH3COO)2O(C10H8N2)2(C5H5N)2](PF6)2, consists of two RuIII ions with a six-coordinate octahedral geometry, bridged by an oxide and two acetate ligands, with a bidentate 2,2′-bipyridine ligand and a pyridine ligand bonding at terminal positions. The Ru—Ru distance and Ru—O—Ru angle are 3.2838 (3) Å and 121.79 (7)°, respectively, and the average Ru—N(pyridine) bond length is 2.164 (8) Å. Several C—H
F, C—HO and C—HN interactions generate a three-dimensional network in the crystal structure. π–π stacking interactions [centroid–centroid distance = 3.6389 (3) Å] between inversion-related 2,2′-bipyridine rings are also observed.

The mononuclear title complex, [VCl2O(C3H8S)2], features a VIV=O double bond [1.5845 (15) Å] in an overall trigonal–bipyramidal coordination environment defined by two Cl− and the S atoms of two (CH3CH2)(CH3)S ligands. In the crystal, pairs of molecules form centrosymmetric dimers via C—HO hydrogen bonds between the methyl C—H group and the oxidovanadium O atom of a neighbouring molecule.
