X-ray diffraction data of twinned gamma-form of o-nitroaniline

<p>The diffraction data are of the gamma-form of o-Nitroaniline, C₆H₆N₂O₃. This compound is known to be polymorphic; the alpha-form is probably amorphous, while the beta- and gamma-forms are crystalline. Difficulties with the unit-cell determination of the gamma-form were reported as a consequence of twinning. These newly recorded diffraction data are of a twinned crystal.</p> <p>The raw data and processing with EVAL are described in details in IUCrData as a Raw Data Letter [Lutz &amp; Kroon-Batenburg, IUCrData (2022].</p> <p>The data were recorded on a Bruker ApexII diffractometer and stored as .sfrm files. They were also converted with Bruker imagesum.py script as part of the APEXII software to full .cbf files.</p>
