Locking high energy 1D chain of dichloromethane molecules containing abnormally short Cl⋯Cl contacts of 2.524 Å inside organic crystals

Abstract

1D helical channels can be created by “sticky” end-mediated formation of 1D helical stacks composed of short cavity-containing helices and are able to host 1D chains of dichloromethane molecules containing extraordinarily short intermolecular Cl⋯Cl contacts of 2.524 Å in length that computationally destabilize the host–guest complex by 14.94 kcal mol⁻¹.
