_platon_squeeze_details
; Electron density in two regions were attributed to a disordered
  hexane molecule for which no suitable model could be found. 
  These regions of electron density were removed from the reflections 
  data using the program SQUEEZE (PLATON), leaving a total void of 
  509.4 angstroms cubed
