MgSrP 3 N 5 O 2 was synthesized at 6 GPa and 1000 °C starting from Mg 3 N 2 , Sr(N 3 ) 2 , PON, and P 3 N 5 utilizing the multianvil technique. By applying NH 4 Cl as mineralizer, single crystals were obtained. MgSrP 3 N 5 O 2 exhibits a novel structure type [ P 2 1 / c (no. 14), a = 6.9404(8), b = 6.6103(7), c = 13.9317(12) Å, β = 118.433(4)°, V = 562.06(10) Å 3 , R 1 = 0.0289, wR 2 = 0.0468]. It is built up of a three‐dimensional P(O, N) 4 tetrahedra network and exhibits an uncommon distribution of ring sizes. Besides 4‐ and 6‐rings, the structure contains 10‐rings as well. PXRD confirms phase purity. MAPLE calculations prove electrostatic plausibility of the crystal structure.
