We report a systematic study of the structure\u2013mechanical properties of 36 p\u2010substituted aryl benzoate ester crystals. They exhibit a range of mechanical responses\u2015elastic, plastic, elastic\u2013plastic, and brittle. By varying the type and position of substituents, we were able to tune intermolecular interaction hierarchies, packing anisotropy, and deformation pathways. Three\u2010point bending experiments, combined with single\u2010crystal X\u2010ray diffraction (SXRD), molecular electrostatic potential (MESP) analysis, Hirshfeld surface (HS) analysis, surface rugosity, attachment energy calculations, and energy\u2010framework analysis, reveal the structural origins of distinct mechanical behaviors. Elasticity in these crystals is linked to the corrugated packing with balanced, reversible dispersive interactions; plasticity, in contrast, is driven by layered architectures with weak interlayer interfaces and accessible slip planes. Elastic\u2013plastic transitions emerge from a subtle balance between stiff intralayer frameworks and stress\u2010sensitive interlayer contacts. The study provides a comprehensive and predictive framework for understanding the structure\u2013mechanical relationships in molecular crystals. It offers robust design principles for engineering organic solids with tailored elastic and plastic properties.<\/jats:p>","DOI":"10.1002\/chem.71257","type":"journal-article","created":{"date-parts":[[2026,6,12]],"date-time":"2026-06-12T10:47:19Z","timestamp":1781261239000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Decoding
