High resolution X-ray diffraction datasets of guanine dichloride

High-resolution single crystal X-ray measurement was carried out on a Bruker APEX II ULTRA single-crystal diffractometer with a TXS rotating anode (Mo Kα, radiation λ = 0.71073 Å) equipped with a CCD-type area detector, multilayer optics and an Oxford Cryostream low temperature attachment set to 100 K. A total of 12412 frames were collected in 44 runs to obtain the high redundancy data. Diffraction data was collected using the ω and φ scan method with a rotation width of 0.5° and the exposure time in the range of 20 - 60 seconds.
