;
 Crystals were grown at 20 \%C from saturated solution in Benzene/Pentane. 
 For data collection the crystal was immersed in a film of perfluoropolyether 
 oil, mounted on a polyimide loop and transferred to stream of cold nitrogen 
 (Oxford Cryostream 800).

;
 Incident beam scaling, empirical absorption correction using spherical 
 harmonics, and outlier rejection was employed as implemented in SADABS. 
 Additional spherical absorption correction with mu*r value set to 0.2 was 
 applied.
