“…The binary parent compound of nitridophosphates is P 3 N 5 . It exhibits a high band gap and has already been applied in electronic devices as an insulator material. − Consequently, it can be expected that ternary or multinary nitridophosphates will show large band gap values as well. Furthermore, the structural diversity of the already known nitridophosphates is comparable to that of nitridosilicates.…”

The isotypic nitridophosphates Ba 3 P 5 N 10 X (X = Cl, I) have been synthesized by high-temperature reaction under pressures between 1 and 5 GPa. The crystal structures of both compounds were solved and refined using single-crystal X-ray diffraction data. Accuracy of the structure determination as well as phase purity of the products were confirmed by Rietveld refinement and FTIR spectroscopy. The band gap values (4.0−4.3 eV) for the direct transitions were determined from UV−vis data using the Kubelka−Munk function and were confirmed by DFT calculations. Both compounds crystallize in the Ba 3 P 5 N 10 Br structure type (space group Pnma (No. 62), Z = 8; Ba 3 P 5 N 10 Cl, a = 12.5182(5) Å, b = 13.1798(5) Å, c = 13.7676(6) Å, R1 = 0.0214, wR2 = 0.0526; Ba 3 P 5 N 10 I, a = 12.6311(7) Å, b = 13.2565(8) Å, c = 13.8689(8) Å, R1 = 0.0257, wR2 = 0.0586) with a tetrahedra network being analogous to the topology of the JOZ zeolite structure type. The crystal structure is built up of all-side vertex-sharing PN 4 tetrahedra leading to a zeolite-like framework with three-dimensional achter-ring channels containing alternately Ba and respective halide atoms. The condensed dreier-, vierer-, and sechser-rings form two different composite building units made up of 3 4 4 2 8 6 -cages. Upon being doped with Eu 2+ , the title compounds exhibit intriguing luminescence properties, which were compared with that of Ba 3 P 5 N 10 Br:Eu 2+ . Upon excitation by near-UV light, nonsaturated color luminescence from multiple emission centers was observed in the orange (X = Cl) and cyan to amber (X = I) spectral range of the visible spectrum.

Nitridophosphates MP2 N4 :Eu(2+) (M=Ca, Sr, Ba) and BaSr2 P6 N12 :Eu(2+) have been synthesized at elevated pressures and 1100-1300 °C starting from the corresponding azides and P3 N5 with EuCl2 as dopant. Addition of NH4 Cl as mineralizer allowed for the growth of single crystals. This led to the successful structure elucidation of a highly condensed nitridophosphate from single-crystal X-ray diffraction data (CaP2 N4 :Eu(2+) (P63 , no. 173), a=16.847(2), c=7.8592(16) Å, V=1931.7(6) Å(3) , Z=24, 2033 observed reflections, 176 refined parameters, wR2 =0.096). Upon excitation by UV light, luminescence due to parity-allowed 4f(6) ((7) F)5d(1) →4f(7) ((8) S7/2 ) transition was observed in the orange (CaP2 N4 :Eu(2+) , λmax =575 nm), green (SrP2 N4 :Eu(2+) , λmax =529 nm), and blue regions of the visible spectrum (BaSr2 P6 N12 :Eu(2+) and BaP2 N4 :Eu(2+) , λmax =450 and 460 nm, respectively). Thus, the emission wavelength decreases with increasing ionic radius of the alkaline-earth ions. The corresponding full width at half maximum values (2240-2460 cm(-1) ) are comparable to those of other known Eu(2+) -doped (oxo)nitrides emitting in the same region of the visible spectrum. Following recently described quaternary Ba3 P5 N10 Br:Eu(2+) , this investigation represents the first report on the luminescence of Eu(2+) -doped ternary nitridophosphates. Similarly to nitridosilicates and related oxonitrides, Eu(2+) -doped nitridophosphates may have the potential to be further developed into efficient light-emitting diode phosphors.

Isotypic imidonitridophosphates MH4P6N12 (M = Mg, Ca) have been synthesized by high-pressure/high-temperature reactions at 8 GPa and 1000 °C starting from stoichiometric amounts of the respective alkaline-earth metal nitrides, P3N5, and amorphous HPN2. Both compounds form colorless transparent platelet crystals. The crystal structures have been solved and refined from single-crystal X-ray diffraction data. Rietveld refinement confirmed the accuracy of the structure determination. In order to quantify the amounts of H atoms in the respective compounds, quantitative solid-state (1)H NMR measurements were carried out. EDX spectroscopy confirmed the chemical compositions. FTIR spectra confirmed the presence of NH groups in both structures. The crystal structures reveal an unprecedented layered tetrahedral arrangement, built up from all-side vertex-sharing PN4 tetrahedra with condensed dreier and sechser rings. The resulting layers are separated by metal atoms.
