In the crystal structure of the ruthenium(III) complex, trans-[RuIII(dcbpy)2Cl2]ClO4 (dcbpy = 2,2′-bipyridine-4,4′-dicarboxylic acid, C12H8N2O4), the RuIII atom lies on an inversion centre, showing a small distortion in its octahedral environment. The Ru—Cl bond lengths are shorter than those present in the analogous trans-ruthenium(II) compound containing the bipyridine ligand. The C—O distances in the two symmetry-independent carboxylic acid moieties of the ligand are similar in one group, but different in the other. This is probably due to the different intermolecular interactions they experience with neighbouring cationic complexes. The hydrogen-bonding interactions in which they are involved form a three-dimensional structure, similar to those found in coordination polymers.
