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. 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. 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. In the tables the empty cells refer to missing values from the literature or to the impossibility to perform calculations.
