A [HN(BH═NH)2]2– Dianion, Isoelectronic with a β-Diketiminate

Abstract

The 1:2 reaction of the Al(III) β-diketiminate dihydride [{DMPnacnac}AlH2] (DMPnacnac = HC{C(Me)N(2,6-Me2-C6H3)}2) (1) with ammonia–borane (NH3BH3) gives the new complex [{DMPnacnac}Al{NHBH)2NH}] (3), whose [HN(BHNH)2]2– dianion is isoelectronic with β-diketiminate anions.
