Metal-like Ductility in Organic Plastic Crystals: Role of Molecular Shape and Dihydrogen Bonding Interactions in Aminoboranes
[post]
2020
unpublished
Ductility, which is a common phenomenon in most metals and metal-based alloys, is hard to achieve in molecular crystals. Organic crystals have been recently shown to deform plastically, but only on one or two faces, and fracture when stressed in any other arbitrary direction. Here, we report an exceptional metal-like ductility in crystals of two globular molecules, BH<sub>3</sub>NMe<sub>3</sub> and BF<sub>3</sub>NMe<sub>3</sub>, with characteristic stretching, necking and thinning with
