摘 要:Three polymorphs(forms I,II and V)of isonicotinamide(INA)were mechanically flexible and exhibited one-dimensional(1 D)plasticity.Anisotropic intermolecular interactions contribute to the plasticity of single crystals:weak dispersive interactions between slip planes such as 1 D columns in forms I and II or 2 D layers in form V were stabilized by strong hydrogen bonds,allowing the layer or column's surface to glide smoothly without hindrance.The disparity of intermolecular interactions on plastic properties of INA polymorphic crystals was confirmed by energy framework analysis,nanoindentation tests and micro-Raman spectroscopy.The crystal which exhibits plastic property provides a promising application in pharmaceuticals and material sciences.
