The hexane solvent molecule could not be resolved due to extensive
disorder and their assumed presence was removed from the overall 
scattering by the PLATON SQUEEZE procedure [Spek (2009). Acta Cryst. 
D65, 148-155]. A total of 105 e was found in each cavity (estimated 
volume 429 \%A^3^),corresponding to approximately two hexane molecules 
per cavity.
