What are metallic or interstitial hydrides? How do they differ from molecular hydrides?

What are interstitial hydrides and how do they differ from molecular hydrides?

Molecular hydrides are

The interstitial hydride is formed by

What are interstitial hydrides and how are they prepared?

Interstitial hydrides are formed by-

Binary compounds of various elements with hydrogen where hydrogen exhibit an oxidation number of (-1) are called binary hydrides. Nature of hydride obtained depends upon electronegativity of the element and hence on the type of bond formed Hydrides are mainly of three classes Ionic, saline or salt like hydrides. Covalent or Molecular hydrides. Metallic or interstitial hydrides. Which of the following form metallic hydrides ?
