Data Tables

Table I reports item number used in the manuscript, chemical formula, space group, superconducting critical temperature as predicted, pressure at which it has has been predicted, hydrogen fraction $H_f$, of the compound from which the $T_c$ value has been extracted.<br><br>Table II reports the item index, chemical formula, {\it networking value} $\phi$, dominant bonding family assigned, and shortest H-H distance for all the compounds. <br><br>Table III reports the item index, chemical formula, total DOS per electron, hydrogen contribution to the DOS per hydrogen atom, and hydrogen fraction of the DOS at the Fermi energy.<br><br> In the tables the empty cells refer to missing values from the literature or to the impossibility to perform calculations.
