; SADABS-2016/2 (Bruker,2016/2) was used for absorption correction, 
 by numerical inegration based on crystal face-indexing followed by 
 semi-empirical correction based on Laue equivalents and multiple scans.  
 wR2(int) was 0.1032 before and 0.0424 after correction. 
 The Ratio of minimum to maximum transmission is 0.8041. 
 The \l/2 correction factor is Not present.
