A disordered half pentane molecule was found in the asymmetrical unit
and could not be satisfactorily refined. The program SQUEEZE (A. L. 
Spek J. Appl. Cryst., 2003, 36, 7-13) was therefore used to remove 
mathematically the effect of the solvent.
The quoted formula and derived parameters are not included the squeezed
solvent molecule.
