The novel nitridophosphate BaP{sub 2}N{sub 4} was obtained by means of high-pressure high-temperature synthesis utilizing the multianvil technique (8GPa, 1400 deg. C). The [PN{sub 2}]{sup -} network is isoelectronic with silica. The structure was solved from synchrotron powder data by a combination of direct methods and difference Fourier synthesis and refined using the Rietveld method (BaP{sub 2}N{sub 4},Pa3-bar ,Z=12,a=10.22992(2)A). BaP{sub 2}N{sub 4} is isotypic with BaGa{sub 2}S{sub 4},BaAl{sub 2}S{sub 4} and the high-pressure phase of CaB{sub 2}O{sub 4}. The P31 solid-state NMR yielded a single sharp resonance at 0.4ppm.
