Attempts to refine peaks of residual electron density as
disordered or partial-occupancy solvent dichloromethane chlorine or
carbon atoms were unsuccessful. The data were corrected for
disordered electron density through use of the SQUEEZE procedure
(Sluis, P. van der; Spek, A. L. Acta Crystallogr. 1990, A46, 194-201)
as implemented in PLATON (Spek, A. L. Acta Crystallogr. 1990, A46,
C34; Spek, A. L. J. Appl. Cryst. 2003, 36, 7-13. PLATON - a
multipurpose crystallographic tool. Utrecht University, Utrecht, The
Netherlands). A total solvent-accessible void volume of 782.7 cubic
Angstroms with a total electron count of 251 (consistent with 6
molecules of solvent dichloromethane, or 1.5 molecules per formula
unit of the hexarhenium complex molecule) was found in the unit cell.
