Crystal engineering is a highly efficient way to create new materials with the desired properties. Energetic cocrystallization has been thriving for ∼10 years since appearance of series TNT-based energetic cocrystals (ECCs). ECCs serve as one important aspect crystal (EMs). This article presents brief overview regarding component, intermolecular interaction, packing structure, main properties, and preparation, well theoretical treatment some issues raised future development. In most cases, properties an ECC are each moderated between those pure components, setting basis tuning by existing molecules, instead synthesizing molecules; meanwhile, there also exceptions, such higher density, detonation or lower impact sensitivity in comparison both components. These exceptions mutated will expand EMs. Generally, currently staying at primary stage, much effort being required solve urgent issues, property evaluation, large-scale fabrication, applications. Still, promising alternative EMs after all, it huge challenge synthesize satisfactory molecule.
