Crystal was attached with Paratone N oil to a 0.3 mm CryoLoop supported 
in a copper mounting pin, then quenched in a cold nitrogen gas stream
from an Oxford Cryosystems Cryostream.

CrysAlisPro 1.171.38.46 (Rigaku Oxford Diffraction, 2015)
Numerical absorption correction based on gaussian integration 
over a multifaceted crystal model. 
Empirical absorption correction using spherical harmonics, 
implemented in SCALE3 ABSPACK scaling algorithm.

_exptl_crystal_preparation
;
Crystals were grown by layered diffusion of methanol into a 
dichloromethane/CS2 solution at RT. The large orange plate crystals 
lost solvent over minutes. A thick plate was cut and a fragment 
mounted rapidly using Paratone N oil.
