Li 14 (PON 3 ) 2 O was synthesized by reaction of phosphoric triamide PO(NH 2 ) 3 with LiNH 2 at 550 °C. It crystallizes in a trigonal structure [ P $\bar {3}$ (no. 147), a = 5.6880(5), c = 8.0855(8) Å, V = 226.55(5) Å 3 , Z = 1] that can be described as a defect variant of the antifluorite structure type. The crystal structure was elucidated from X‐ray powder diffraction data and corroborated by FTIR and solid‐state NMR spectroscopy. Li 14 (PON 3 ) 2 O is composed of non‐condensed PON 3 6– tetrahedra and O 2– ions that are surrounded by tetrahedrally coordinated Li + . This is the first example of an ortho ‐oxonitridophosphate.
