Phase composition in AlNaH4 doped with FeCl2 was studied by Mossbauer spectroscopy and X-ray diffraction and stabilities in Ar and air were compared. The results show that the hydride disappeared during the exposition to air. The major sodium alanate hydride traps gaseous impurities and transforms to Na2CO3 and Al(OH)(3).
