WebA true hydride (H-) is one which forms either an ionic or covalent bond with another atom. An example would be HBr or EtOH. However, interstitial hydrides do not form either of these true bonds, which contribute to the formation of an entirely new molecule. Instead, they form a metallic “bond” which does not give rise to a new compound.
