One badly resolved regions of residual electron density was tentatively 
identified as an approximately 50/50 mixture of one molecule of 
diethyl ether and one molecule of CH2Cl2, 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 solvents.
Derived parameters such as the formular weight correspond to two
molecules of diethyl ether and two molecules of CH2Cl2 per cell.
