4-Bromobenzonitrile was crystallised by sublimation under vacuum. The crystals show highly flexible plastic bending along two perpendicular faces when a mechanical force is applied. The rare occurrence of bending along two perpendicular faces results in twisting or helix formation.
4-溴苯甲腈通过真空升华结晶。当施加机械力时，晶体在两个相互垂直的面上表现出高度灵活的塑性弯曲。沿两个相互垂直的面发生弯曲的情况很少见，会导致扭曲或螺旋形成。
