BaAl2(NH2)8 center dot 2NH3 was synthesized starting from an intermetallic phase with nominal composition Al2Ba 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) angstrom, Z = 1, 1829 reflections, 65 parameters, wR2 = 0.07) was solved on the basis of single-crystal X-ray diffraction data. BaAl2(NH2)8 center dot 2NH3 contains isolated Al(NH2)4-tetrahedra forming two different types of channels along [001].
