The vast majority of these Grimm\u2013Sommerfeld analogue compounds crystallize in the <jats:italic>\u03b2<\/jats:italic>\u2010NaFeO<jats:sub>2<\/jats:sub> structure, although a second arrangement in space group <jats:italic>Pmc<\/jats:italic>2<jats:sub>1<\/jats:sub> is predicted to be a viable alternative. Despite extensive theoretical and experimental studies, this structure has so far remained undiscovered. Herein, we report on BeGeN<jats:sub>2<\/jats:sub> in a <jats:italic>Pmc<\/jats:italic>2<jats:sub>1<\/jats:sub> structure, synthesized from Be<jats:sub>3<\/jats:sub>N<jats:sub>2<\/jats:sub> and Ge<jats:sub>3<\/jats:sub>N<jats:sub>4<\/jats:sub> using a high\u2010pressure high\u2010temperature approach at 6\u2005GPa and 800\u2009\u00b0C. The compound was characterized by powder X\u2010ray diffraction (PXRD), solid state nuclear magnetic resonance (NMR), Raman and energy dispersive X\u2010ray (EDX) spectroscopy, temperature\u2010dependent PXRD, second harmonic generation (SHG) and UV\/Vis measurements and in addition also compared to its lighter homologue BeSiN<jats:sub>2<\/jats:sub> in all mentioned analytic techniques.
