The final part of the analysis deals with the dynamic behaviour of the OSDA molecules, with special emphasis on the presence of hydrogen bonds and their evolution with temperature. Due to significant disorder of the OSDAs at 298 K and 573 K, the AIMD average structures provide only a limited amount of information in this regard. The analysis presented here on the F-N and H-O RDFs, because these quantities provide a convenient means to assess the most relevant features of the OSDA dynamics. For the F-N RDFs, only fluoride anions and nitrogen atoms lying approximately in one plane perpendicular to the c axis were considered, leading to four, rather than six, F-N contacts in the distance range up to ~10 Å (Figure ).
