The first carbaalanate consists of a carbaalane dianion [(AlH) 8 (CCH 2 t Bu) 6 ] 2− that is coordinated through hydride bridges to two lithium ions on opposite sides of the cluster (see picture). Additionally, the lithium ions are each further coordinated to a neutral [ t BuCH 2 C(AlH 2 ⋅NMe 3 ) 3 ] unit. In this arrangement, the lithium ion prevents condensation of the [ t BuCH 2 C(AlH 2 ⋅NMe 3 ) 3 ] units.
