We use interchangeably the expressions 'reaction energy' and 'reaction enthalpy'; earlier calculations for various hydride materials show that reaction enthalpy typically differs only very little from the ZPVE-corrected reaction energy, due to cancelling of these differences for all substrates and products together:

Note, conductivity and superconductivity usually requires presence of atomic bridges between the electron-exchanging centers in the crystal structure of an extended solid. Here we postulate that, paradoxically, certain molecular hydride materials might be even better superconductors than those hydrides which contain the direct M-H-M bridges
