A New High-Pressure High-Temperature Phase of Silver Antimonate AgSbO₃ with Strong Ag-O Hybridization.

ABSTRACT: We report on a new polymorph of silver antimonate AgSbO₃ discovered with the use of high-pressure high-temperature synthesis at 16 GPa and 1380 °C. The crystal structure is determined from X-ray powder diffraction, and we find this new high-pressure phase crystallizes in monoclinic space group C2/c with the following values: a = 8.4570(3) Å, b = 9.8752(3) Å, c = 8.9291(3) Å, β = 91.1750(12)°, and V = 745.56(4) ų. We synthesized the high-pressure (16 GPa) AgSbO₃ phase from the ilmenite phase as a precursor. This high-pressure monoclinic AgSbO₃ consists of a three-dimensional network of corner- and edge-sharing SbO₆ octahedra with channels along the c-direction containing Ag atoms. We als
