Abstract

Nitridophosphates and imidonitridophosphates show intriguing structural diversity, including unprecedented structure types. Highly condensed strontium imidonitridophosphate SrP3N5NH has been synthesized at 8GPa and 1100 degrees C using a high-pressure high-temperature approach starting from stoichiometric amounts of Sr(N-3)(2), P3N5 and NH4Cl. Herein, NH4Cl was used as a hydrogen source and as a precursor for in situ formation of SrCl2, which acts as mineralizer and facilitates growth of single-crystals with a diameter of 30m. SrP3N5NH (P2(1)/c (no.14), a=5.01774(2), b=8.16912(4), c=12.70193(5)angstrom, =101.7848(3)degrees, Z=4) adopts an unprecedented network structure, represented by the point symbol (3.4.5.6.7(2))(3.4.5.7(2).8)(3.6.7(3).8). This unique three nodal P/N(H) network is stabilized by moderately strong hydrogen bonds causing a structure-directing effect, which has not yet been reported for imidonitridophosphates.
