A review of the structural existing data on Hg-1201 shows evidence of non stoichiometry of the sample. In this compound not only oxygen but also Hg seems to be released or, perhaps, substituted. So, the production of bulk samples with optimal oxygen doping and homogeneus Hg content could be profitable for the study of the effect of the Hg solubility, allowing to confirm its existence till to room temperatures, and to test the effect of Hg impoverishment on other critical superconducting parameter different from Tc.

Abstract
A review of the structural existing data on Hg-1201 shows evidence of non stoichiometry of the sample. In this compound not only oxygen but also Hg seems to be released or, perhaps, substituted. So, the production of bulk samples with optimal oxygen doping and homogeneus Hg content could be profitable for the study of the effect of the Hg solubility, allowing to confirm its existence till to room temperatures, and to test the effect of Hg impoverishment on other critical superconducting parameter different from Tc.
