Crystal Structure and Characterization of Salicylic Acid-benzene Azimide Cocrystal

摘要

A new single crystal of 1:1 salicylic acid-benzene azimide was determined and cha- racterized. It belongs to space group P21/n with a = 13.8085（13）, b = 5.3846（4）, c = 16.7063（13） and β = 102.331（9）°. Crystals of the title compound, C7H6O3·C6H5N3, were obtained by cocrys- tallization. FT-IR, Raman spectroscopy and TGA-DTA were applied to characterize the title compound as supplemental evidence to prove the formation of the crystal. Our work describes the solubility of the crystal by considering the equilibria between the crystal, components, and solution mixture.
