✦ Synopsis

a Nanocrystal by Automated Electron Diffraction Tomography. -The title compound is synthesized from a mixture of SrS, OP(NH2)3, SP(NH2)3, and NH4Cl (silica glass ampule, 750 °C, 72 h). The samples are characterized by powder XRD, SEM, TEM, FTIR, and 31 P MAS NMR spectroscopy. SrP3N5O crystallizes in the orthorhombic space group Pnma with Z = 16. The structure contains corrugated ∞ 2 [P 3 N 5 O 2-] layers consisting of linked, triangular columns of P(O,N)4 tetrahedra. Sr 2+ ions are located between the layers and show six-, eight-, and ninefold coordination. -(SEDLMAIER, S.
