    • Acentric Cc, a proper subgroup of C′2/c, was also considered as a possible candidate. The complexity of the structure of species 3 within such a description (requiring the introduction of stiff restraints in order to reach convergence to a chemically significant model) and the absence of a cristallochemical clue (suggesting that a centrosymmetric structure is not tolerable), together with the presence of a dominating scatterer (the Hg ion), makes it impossible to assess from powder data only, the significance of the agreement factor lowering observed upon doubling the number of free structural parameters; therefore, the centric model was eventually adopted, which we believe to be consistent with all chemical and crystallographic data in our hands.
