The reaction of AlMe 3 or ZnMe 2 with hppH (hppH=1,3,4,6,7,8‐hexahydro‐2 H ‐pyrimido[1,2‐ a ]pyrimidine) and then with t BuLi affords [Li 8 (H) m (hpp) 6 ] n + [X] − n , X=[Zn t Bu 3 ], m = n =1 (the cation core of which is shown); X=[Li(Me 2 Al t Bu 2 ) 2 ], m =0, n =2, as the major product in each case. These data reveal that non‐aromatic heterocycle hppH and ZnMe 2 can be employed to generate novel hydride‐encapsulation main‐group‐metal clusters, and that related polylithium architectures can also incorporate a central void.
