Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>BaAl₂(NH₂)₈<bold>·</bold>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 (<italic>R</italic><tex-math notation="tex"><![CDATA[$\bar{3}$]]></tex-math><inline-graphic xlink:href="ark:/27927/pgg21msxq84" mimetype="image" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /><italic>c </italic>(no. 167), <italic>a</italic> = 15.7370(17), <italic>c</italic> = 28.804(6) Å, <italic>Z</italic> = 1, 1829 reflections, 65 parameters, <italic>wR</italic>₂ = 0.07) was solved on the basis of single‐crystal X‐ray diffraction data.
