 Refined as an inversion twin.
Refined as a 2-component inversion twin.  The absolute configuration was 
initially assigned using the Flack method.  The assignment was confirmed by 
use of both the Hooft y-parameter (0.06(7)) (Hooft, Straver and Spek, 2008) 
and Parsons Z coeffient (0.01(5)) (Parsons, Flack and Wagner, 2013).
