    Anion-deficient pyrochlore type oxynitrides Eu2Mo 2O5-xN2+x-δ are obtained from ammonolysis of the pyrochlore Eu2Mo2O7. However, these phases are not obtained when scheelite type EuMoO4 is used, demonstrating that the former reaction proceeds under topochemical control. This implies that other distinct new stoichiometric oxynitrides may be discovered from ammonolysis of mixed metal oxide precursors with appropriate structures. © 2010 American Chemical Society.
