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.
根据X-射线衍射数据,结晶3-(苯并恶唑-2-基硫基)-3-苯基-2-丙烯腈是基本上非平面的Z-异构体。由于 π-π 堆叠,所得单晶具有层状结构。1H NMR 数据证明溶解在氯仿中的样品中存在少量 E-异构体。
