A badly disordered pentane molecule was found in the 
asymmetrical unit and could not be satisfactorily refined. The program 
SQUEEZE (Spek, A.L. (2015). Acta Cryst. C71, 9-18) was therefore used to
remove mathematically the effect of the solvent.
The quoted formula and derived parameters are not included the squeezed
solvent molecule.
