Single-crystal X-ray diffractometry data for a sample of Ni(dppe)Cl₂ collected on beamline I19-2 at Diamond Light Source with an Eiger 2X 4M with CdTe sensor

Single-crystal X-ray diffraction data were collected for Ni(dppe)Cl₂ (dppe = 1,2-bis(diphenylphosphino)ethane) on beamline I19 at Diamond Light Source. Measurements were performed on a four-circle Newport diffractometer located in Experimental Hutch 2 (EH2), equipped with an Eiger 4M CdTe photon-counting pixel array detector. Data were collected using X-ray radiation of wavelength 0.4859 Å (Ag K-edge) on 7 April 2025. Temperature control was provided by an Oxford Cryostream 700 series, with data collected at 150 K. The dataset consists of a single 350° scan acquired with a step size of 0.2° per image.
