Inclusion compounds
WebTo form conventional urea inclusion compounds, guest molecules act as a template, while hydrogen-bonded urea molecules are arranged along the guests76. Urea molecules adopt a helical rotation, either right-handed or left-handed77, along the hexagonal tunnels. In urea inclusion compounds, the guest molecules are densely packed within and along ... WebThe necessary quantity of urea for the formation of inclusion compounds varies from about 1 to 0.8 mole of urea per methyl- and methylene group in a carbon chain. The urea is …
