Aluminium borohydride

Aluminium borohydride in the gaseous state has a positive enthalpy of formation, so it can be assumed to be rather unstable. It combusts spontaneously in contact with air, but detonates if water traces are present. The same thing happens in contact with water at 20°C.

Of unknown structure, it remains stable up to 100°, but beyond, decomposes into aluminium and hydrogen. It reacts with diborane to form aluminium borohydride. 

Beryllium and Aluminium borohydrides These are covalent and volatile. In these the [BH4]- groups acts as a ligand. One or more H atoms in a [BH4]- act as a bridge and bond to the metal, forming a three centre bond with two electrons. The structures are as... 

Z-Ray data on aluminium borohydride between —60 and — 150°C confirm the existence of two polymorphic modifications. Thermographic measurements indicate that the compound melts at — 64°C, and that the phase transition occurs at —78 °C. No change takes place in the i.r. spectrum between —70 and — 90 °C, however. ... 

The reaction of aluminium borohydride with tetraethylammonium chloride or bromide gives crystalline compounds (Et4N)[Al(BH4)3X] (X = Cl or Br). These are readily soluble irj ben2ene, and could be characterized by X-reLy powder diffraction and i.r. spectroscopy. These confirmed the presence of the anion shown, rather than a mixture of [A1(BH4)4] and AIX. When X = Cl, i-CAlCl) was seen at 495 cm. ...
