What is the structure of complex hydrides?
Complex hydrides are compounds that contain transition metal–hydrogen complexes in their structure and usually offer very high volumetric densities. A maximum value of 150 kg. m−3 has been reported for Mg2FeH6 and Al(BH4)3. The gravimetric density is also larger than that found in metal hydrides (e.g. 5.5 wt.
How are metal hydrides formed?
Metal hydrides are formed when metal atoms bond with hydrogen to form stable compounds. A large amount of hydrogen per unit volume can be extracted, so the storage density is good despite the fact that they can be heavy. They are often used as powders to maximize the surface area–to-mass ratio.
How do metal hydrides work?
Metal hydrides are chemical compounds formed when hydrogen gas reacts with metals. When these metal powders absorb hydrogen to form hydrides, heat is released. Conversely, when hydrogen is released from a hydride, heat is absorbed.
What is polymeric hydride?
When the hydride molecules get joined and form a polymeric structure then they are known as a polymeric hydride. In the case of \[Mg{H_2}\] magnesium forms a normal bond with hydrogen to form hydride. But in this molecule, the total valence electron is only four.
What is the formula of Aluminium hydride?
AlH3
Aluminium hydride/Formula
What do you mean by hydrides?
In chemistry, a hydride is formally the anion of hydrogen, H−. For inorganic chemists, hydrides refer to compounds and ions in which hydrogen is covalently attached to a less electronegative element. In such cases, the H centre has nucleophilic character, which contrasts with the protic character of acids.
How do metal hydrides store hydrogen?
SOLID-H hydrogen storage containers are filled with metal powders that absorb and release hydrogen (metal hydrides). The most popular SOLID-H containers supply a few atmospheres of hydrogen gas pressure at room temperature. This is the safest method known for storing flammable hydrogen gas.

What is saline hydride?
Saline hydrides (also known as ionic hydrides or pseudohalides) are compounds form between hydrogen and the most active metals, especially with the alkali and alkaline-earth metals of group one and two elements. In this group, the hydrogen acts as the hydride ion (H−). They bond with more electropositive metal atoms.
