Abstract Owing to intriguing materials properties non‐metal nitrides are of special interest for both, solid‐state chemistry and materials science. Mixed ternary non‐metal nitrides, however, have only been sparsely investigated, as preparative chemistry lacks a systematic access, yet. Herein, we report on the highly condensed boron phosphorus nitride BP 3 N 6 , which was synthesized from (PNCl 2 ) 3 , NH 4 N 3 and h‐BN in a high‐pressure high‐temperature reaction. By increasing partial pressure of HCl during synthesis using NH 4 Cl, single‐crystals of BP 3 N 6 up to 80 μm in length were obtained. The unprecedented framework‐type structure determined by single‐crystal XRD blends structural motifs of both, α‐P 3 N 5 and c‐BN, rendering BP 3 N 6 a double nitride. The compound was further investigated by Rietveld refinement, EDX, temperature‐dependent PXRD, FTIR and solid‐state NMR spectroscopy. The formation of BP 3 N 6 through use of reactive precursors exemplifies an innovative access to mixed non‐metal nitrides.
