Using first-principles ca.cula.ions a.d crysta. structure sea.ch methods, we found tha. ma.y cova.ently bonded molecules such a. H2, N2, CO2, NH3, H2O a.d CH4ma. rea.t with Na. l, a.prototype ionic solid,a.d form sta.le compounds under pressure while reta.ning their molecula. structure. These molecules,despite whether they a.e homonuclea. or heteronuclea., pola. or non-pola., sma.l or la.ge, do not show strong chemica. intera.tions with surrounding Na.a.d Cl ions. In contra.t, the most sta.le molecule a.ong a.l exa.ples, N2, is found to tra.sform into cyclo-N5-a.ions while rea.ting with Na. l under high pressures. It provides a.new route to synthesize penta.ola.es, which a.e promising green energy ma.eria.s with high energy density. Our work demonstra.es a.unique a.d universa. hybridiza.ion propensity of cova.ently bonded molecules a.d solid compounds under pressure. This surprising miscibility suggests possible mixing regions between the molecula. a.d rock la.ers in the interiors of la.ge pla.ets.
