title: Anomeric effect for a 2,5,7-triazabicyclo[2.2.1]heptane derivative.
abstract: A new member of the polyazapolycyclic family of compounds, namely N(3),N(6),2,5,7-pentaphenyl-2,5,7-triazabicyclo[2.2.1]heptane-3,6-diamine xylene solvate, C(34)H(31)N(5).C(8)H(10), was synthesized for the first time and the crystal structure is reported. There are no hydrogen bonds joining the molecules. All four chiral C atoms have the same absolute configurations. With regard to the four N-C-N groups, anomeric effects are observed to cause a reduction of C-N bond length and N-atom pyramidality.
