 A considerable amount of electron density attibutable to partially 
 disordered CH2Cl2 solvent molecule was removed with the SQUEEZE option
 of PLATON (Spek, A. L. (2005). PLATON, A Multipurpose Crystallographic
 Tool, Utrecht University, Utrecht, THe Netherlands).
 This solvent molecule is,however, included in the reported
 chemical formula and derived values (e.g. formula weight, F(000), etc).
