Treatment of H3AlNMe3 with 1,3,5-trimethylhexahydro- 1,3,5-triazine (tmtz) yields trigonal bipyramidal, monomeric [H 3Al(tmtz)2], 1, or polymeric [H3Al(tmtz)] ∞, 2, which undergo N-CH2 cleavage at ca. 123°C; nitrogen-atoms in 1 and 2 are in apical positions, as also established for polymeric [H3Al(N,N,N′,N′-tetramethylpropylenediamine)] ∞, in accordance with ab initio molecular orbital calculations on the model system H3Al(NH3)2.
