Expanding the Ambient-Pressure Phase Space of CaFe₂O₄-Type Sodium Postspinel Host-Guest Compounds.

ABSTRACT: CaFe₂O₄-type sodium postspinels (Na-CFs), with Na⁺ occupying tunnel sites, are of interest as prospective battery electrodes. While many compounds of this structure type require high-pressure synthesis, several compounds are known to form at ambient pressure. Here we report a large expansion of the known Na-CF phase space at ambient pressure, having successfully synthesized NaCrTiO₄, NaRhTiO₄, NaCrSnO₄, NaInSnO₄, NaMg_0.5Ti_1.5O₄, NaFe_0.5Ti_1.5O₄, NaMg_0.5Sn_1.5O₄, NaMn_0.5Sn_1.5O₄, NaFe_0.5Sn_1.5O₄, NaCo_0.5Sn_1.5O₄, NaNi_0.5
