We thank Diamond Light Source for access to synchrotron radiation facilities (proposal mx14739), and the staff of beamline I03 for assistance with crystal testing and data collection. This work was supported by the Council of Education of Junta de Castilla y León (Spain) and the European Regional Development Fund, grant SA017U16.

Data were collected on a single crystal at the beamline i03 of the Diamond synchrotron facility (Didcot, UK) using radiation of 0.99998 Å wavelength and a PILATUS3 6M detector. The dataset consists of 3600 images (0.1 degree oscillation per image). Data extend to ~1.1 Å resolution.
