Borohydride-containing coordination polymers: synthesis, air stability and dehydrogenation.

ABSTRACT: Control of the reactivity of hydride (H^-) in crystal structures has been a challenge because of its strong electron-donating ability and reactivity with protic species. For metal borohydrides, the dehydrogenation activity and air stability are in a trade-off, and control of the reactivity of BH₄ ^- has been demanded. For this purpose, we synthesize a series of BH₄ ^--based coordination polymers/metal-organic frameworks. The reactivity of BH₄ ^- in the structures is regulated by coordination geometry and neighboring ligands, and one of the compounds [Zn(BH₄)₂(dipyridylpropane)] exhibits both high dehydrogenation reactivity (1.4 wt% at 179 °C) and high air stability (50 RH% at 25 °C, 7 days).
