Abstract

A sequence of two phase transitions at 85.3±0.6 K and 72.6±0.4 K is observed in hexagonal Cs₃Sb₂I₉. The NQR spectra of ¹²⁷I are analyzed, optical polarization studies are made, and the thermal properties, linear expansion coefficients, and stiffness constants are measured over a broad range of temperatures below room temperature.
