Teamwork : Structural characterization of the first dinuclear mercury(II) complex with a regular porphyrin reveals dissymmetry induced by binding of dimethyl sulfoxide molecules to the metal ions, which form two allosterically connected binding sites (see structure; gray C, orange Hg, blue N, red O, yellow S). The cooperativity of the metal insertion can be tuned, either positively or negatively, by the presence of a base or by the interaction with exogenous ligands.
