 Two badly resolved regions of residual electron density around
 0.5 0 0.5 and 1 0.5 1 were  tentatively identified as disordered CH2Cl2
 molecules but could not be refined satisfactorily. For this reason the
 program SQUEEZE (part of the PLATON suite; A. Spek, University of
 Utrecht, Netherlands, 2009) was used to remove mathematically the
 effects of the solvent. Derived parameters such as the formular weight
 correspond to two CH2Cl2 molecules per cell.
