BaAl 2 (NH 2 ) 8 · 2NH 3 was synthesized starting from an intermetallic phase with nominal composition Al 2 Ba under ammonothermal conditions in a stainless‐steel autoclave at 823 K and 245 MPa. Single crystals were grown on aluminum substrates and prepared under low‐temperature conditions. The crystal structure ( R $\bar{3}$ c (no. 167), a = 15.7370(17), c = 28.804(6) Å, Z = 1, 1829 reflections, 65 parameters, wR 2 = 0.07) was solved on the basis of single‐crystal X‐ray diffraction data. BaAl 2 (NH 2 ) 8 · 2NH 3 contains isolated Al(NH 2 ) 4 ‐tetrahedra forming two different types of channels along [001].
