Abstract

The gallium(III) nitridophosphate-oxide Ga-16/3[P12N24]O-2 was synthesized by metathesis reaction between GaF3 and LiPN2. The crystal structure was elucidated by electron crystallography and powder X-ray diffraction, comparing both approaches. This reveals a partially collapsed sodalite-type structure (space group I 4? ${\bar{4}}$ 3m, a=8.1585(2) angstrom) with a tilt angle phi of similar to 33 degrees. Vertex-sharing PN4 tetrahedra build up a sodalite network that hosts gallium(III) cations and oxide anions. Gallium forms bonds to further three N atoms. The structure model is confirmed by EDX analyses, IR spectroscopy and bond valence sum calculations.
