Is Non Stoichiometric Hydrides?

Non stoichiometric hydrides are formed by the reaction of Hydrogen molecules and d-block and f-block and do not follow law of constant proportions. The metal and hydrogen are combined in the fractional form. ... Non stoichiometric hydrides are chemical inorganic compounds and its physical state is solid.

Are metal hydrides non-stoichiometric?

Metallic hydrides are usually nonstoichiometric compounds, as expected from their relatively low heats of formation and the mobility of hydrogen.

Are ionic hydrides non-stoichiometric?

Non-Stoichiometric hydrides are hydrogen-deficient compounds formed by the reaction of dihydrogen with d-block and f-block elements. These hydrides do not follow the law of constant composition. ... These hydrides are ionic in nature. Hydride ions have comparable sizes (208 pm) with alkali metal ions.
