چکیده

Mechanochemical reactions between KBH4 and KBF4 result in the formation of potassium fluoroborohydrides K(BH(x)F(4-x)) (x = 0-4), as determined by (11)B and (19)F solid state NMR. The materials maintain the cubic KBH4 structure. Thermogravimetric (TG) data for a ball-milled sample with KBH4 : KBF4 = 3 : 1 are consistent with only desorption of hydrogen.
