Fig. 2. (a) 1·2CH3CN optical reflectivity measurements between 288 K and 373 K. (b) Optical image of a 1·2CH3CN crystal at room temperature (yellow), after heating and subsequent loss of acetonitrile molecules (1, orange) and after exposure to acetonitrile (yellow). (c) 1·2CH3CN infrared spectra at different temperatures. (d) DSC measurements of a 1·2CH3CN crystal between 288 K and 373 K. (e) TGA curve measured between 303 K and 373 K (black line). The blue line represents the derivative weight.
