Irreducible three-proton interactions are shown to be essential in the development of the metal hydrogen structure. Possible manifestations of the three-ion interactions in the structure of quickly quenched metallic systems are discussed. Existence of amorphous metals is related to manifestations of the three-ion interactions in non-equilibrium conditions when amorphisation front travels through a liquid metal.8 pages, RevTex, 4 figuresMaterials Sciencetext
