Alert level A
PLAT601_ALERT_2_A Structure Contains Solvent Accessible VOIDS of .     419.00 A   3

Author Response: As noted in the Experimental section, solvent of crystallization (benzene and/or pentane) was found but was so severely disordered about the 3-fold axis that its identity could not be confidently determined nor could it be modeled in any satisfactory manner. The disordered electron density was therefore removed with PLATON SQUEEZE.
