A bulk solid comprising a metal hydride of the formula (I):
- Mn(M2)zHxRyLn (I)
- wherein
- M2 is one or more metals (other than manganese), which have a total content of z;
- R, if present, is an organic group;
- L is a Lewis base;
- n is 0 to about 1;
- x is about 1.5 to about 10;
- y is 0 to about 0.25;
- and
- z is 0 to about 1;
- wherein the metal hydride is stable as a bulk solid at room temperature, and
- wherein the metal hydride is capable of storing molecular hydrogen in an amount of at least 2% (based upon 100% total weight of the metal hydride without hydrogen stored in it) and reversibly releasing the hydrogen.
