Highlighted illustration

Cover illustration: 1,2-Diamines tend to adopt a conformation in which the arrangement of electron pairs is antiperiplanar. This behaviour is known as the `rabbit-ears effect', however it can be avoided by restriction of the 1,2-diamine in cyclic molecules. The crystal studied, C₂₁H₂₄F₂N₂O₂, was a meso compound obtained by the reaction of the aminal (2S,7R,11S,16R)-1,8,10,17-tetraazapentacyclo[8.8.1.1^8,17.0^2,7.0^11,16]cosane with 4-fluorophenol. The imidazolidine ring has a twisted conformation with the lone pairs of the N atoms disposed in a syn isomerism, making this compound an exception to the typical `rabbit-ears effect' in 1,2-diamines.
