摘要：

Variegated decomposers: The synthesis of the first mixed alkali metal borohydride, which contains lithium and potassium, is presented. LiK(BH 4)2 (see picture; K crimson, Li yellow, B green, H gray) has a crystal structure similar to LiBH4, and a thermal decomposition temperature between those of LiBH4 and KBH4. Using this route, the hydrogen desorption thermodynamics of complex hydrides can be easily tailored. (Figure Presented). © 2008 Wiley-VCH Verlag GmbH & Co. KGaA.
