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