Electron density peaks were located during structural refinement. These were believed to be a disordered hexane molecule per unit of the title complex. Several attempts were made to model the solvent molecule but were not successful. 
The SQUEEZE option in PLATON (Spek, 2003) indicated there was a solvent cavity of volume 513.0A^3^ containing approximately 109 electrons. This contribution to the electron density was removed from the observed data uisng the SQUEEZE option in PLATON (Spek, 2003). 

Similar treatments of disordered solvent molecules were carried out by St\"ahler et al. (2001),  Cox et al. (2003), Mohamed et al. (2003) and Athimoolam et al. (2005).

The following automatic conversions were performed:

'_symmetry_cell_setting' value 'Triclinic' changed to 'triclinic'
according to the built-in table from CIF Core dictionary named
'cif_core.dic' version 2.4.1 from 2010-06-29.

'_exptl_crystal_density_meas' value 'not measured' was changed to '?'
- the value is perceived as not measured.
