Abstract
The crystal structure of nequinate has been solved and refined using synchrotron X-ray powder diffraction data and optimized using density functional techniques. Nequinate crystallizes in the space group P21/c (#14) with a = 18.35662(20), b = 11.68784(6), c = 9.06122(4) Å, β = 99.3314(5)°, V = 1918.352(13) Å3, and Z = 4. The crystal structure is dominated by the stacking of the approximately planar molecules. N–H⋯O hydrogen bonds link adjacent molecules into chains parallel to the b-axis. The powder pattern has been submitted to ICDD for inclusion in the Powder Diffraction File™ (PDF®).
期刊介绍：
Powder Diffraction is a quarterly journal publishing articles, both experimental and theoretical, on the use of powder diffraction and related techniques for the characterization of crystalline materials. It is published by Cambridge University Press (CUP) for the International Centre for Diffraction Data (ICDD).
