Sodium aluminium hydride

Sodium aluminium hydride or sodium alanate is an inorganic compound with the chemical formula NaAlH₄. It is a white pyrophoric solid that dissolves in tetrahydrofuran (THF), but not in diethyl ether or hydrocarbons. It has been evaluated as an agent for the reversible storage of hydrogen and it is used as a reagent for the chemical synthesis of organic compounds. Similar to lithium aluminium hydride, it is a salt consisting of separated sodium cations and tetrahedral AlH₄ anions.
