Beryllium borohydride is an inorganic compound with the chemical formula Be[BH4]2.

[2] Beryllium borohydride is formed by the reaction of beryllium hydride with diborane in an ether solution.

It can also be formed by the reaction of beryllium chloride and lithium borohydride in a sealed tube at 120 °C:[2] The chemical formula of beryllium borohydride can be written as Be2+([BH4]−)2.

[2][3] The borohydride ions, [BH4]−, adopt a tetrahedral geometry.

[3] Beryllium is 6-coordinate and adopts a distorted trigonal prismatic geometry.
