The oxonitridophosphates LixH12-x-y+z[P12OyN24-y]Cl-z (1a) and LixH12-x-y+z[P12OyN24-y]Br-z (1b) were obtained by the reaction of Li2S, SP(NH2)(3), OP(NH2)(3) and NH4Cl or NH4Br, respectively, in closed ampoules at 700 degreesC in a tube furnace. The crystal structure of LixH12-x-y+z[P12OyN24-y]X-z (X = Cl, Br) (1) was elucidated by means of X-ray diffraction of single crystals of 1a and of mixed single crystals lab (Pna2(1); a 475.3(1) pm, b = 1420.8(3) pm, c 820.3(2) pm (1a) and a 476.6(1) put, b = 1426.3(3) pm, c 823.5(2) pm (1ab), respectively; Z = 1) and via X-ray diffraction, neutron diffraction, electron diffraction and solid state NMR spectroscopy of powder samples of 1a. The anionic network is composed of corner-sharing P(O, N)(4)-tetrahedra forming 12-ring channels. The lithium and the halide ions are located in these channels. The chemical composition of the samples was determined by EDX analysis and chemical elemental analysis. IR and Raman spectroscopic properties as well as the thermal behaviour were investigated. Impedance spectroscopic measurements showed a lithium ion conductivity.
