Molecular Assemblies from Imidazolyl-Containing Haloalkenes and Haloalkynes: Competition between Halogen and Hydrogen Bonding
Abstract
1-(3-Iodopropargyl)imidazole and 1-(2,3,3-triiodoallyl)imidazole self-assemble to give polymeric chains as a result of N...I halogen bonding. However, these interactions are not sufficiently strong to compete with hydrogen bonding. N-H...O and N-H...N interactions govern the molecular arrangement in the 1:1 cocrystal of 1-(2,3,3-triiodoallyl)imidazole and morpholinium iodide.
