An XRD Study of Molecular and Crystalline Structures of (Z)-3-(Benzoxazol-2-Ylthio)-3-Phenyl-2-Propenonitrile and an 1H NMR Study of Its E/Z Isomerization in Solutions

详细

According to X-ray diffraction data, crystalline 3-(benzoxazol-2-ylthio)-3-phenyl-2-propenonitrile is a substantially nonplanar Z-isomer. The resulting single crystal has layered structure as a result of π–π stacking. ¹H NMR data testify small amounts of E-isomer in the samples dissolved in chloroform.
