Article Abstract

The first nitridogermanates(III) Ca [Ge N ] and Sr [Ge N ] were synthesized from sodium flux and structurally characterized by powder and single crystal X-ray diffraction, respectively. They crystallize isostructurally to each other and homeotypic to Ca [Cr N ]H in space group R . They feature unprecedented, mutually isolated, ethane-like [Ge N ] anions in a staggered conformation. The compounds are semiconductors according to resistivity measurements and electronic structure calculations, yielding band gaps of 1.1 eV for Ca [Ge N ] and 0.2 eV for Sr [Ge N ].
