Differential scanning calorimetric and Raman studies of a phase transition in [C3H7NH3]2SiF6

Abstract A new structural phase transition was detected at low temperatures in [C3H7NH3]2SiF6 by means of differential scanning calorimetry; the basic thermodynamic data were determined for this transition. The Raman spectra of this compound were recorded from ambient temperature through the phase transition at 223 K. The observed phase transition may be of the order–disorder type and probably of first‐order character. Copyright © 2004 John Wiley & Sons, Ltd.
