The average structures of 2,3-diazabicyclo[2.2.1]hept-2-ene and 2,3-diazabicyclo[2.2.2]oct-2-ene

The average molecular structures of 2,3-diazabicyclo[2.2.1]hept-2-ene and 2,3-diazabicyclo[2.2.2] oct-2-ene have been determined by electron diffraction in the gas phase. The structural parameters were obtained by applying a least squares analysis on the molecular scattering intensity functions. For 2,3-diazabicyclo[2.2.1]hept-2-ene, C_s symmetry was assumed in calculating the geometry of the molecule. The parameters thus determined are: N₃=N₂ = 1.221 Å, N₃- C₄ = 1.445 Å, C₄-C₅ = 1.538 Å, C-H_(ave.) = 1.112 Å, < C₁N₂N₃ = 116.3°, < N₃C₄C₅ = 105.2°, < C₁C₄C₅ = 71.5°, C₄-C₇ = 1.547 Å, C₅-C₆ = 1.530 Å, < C₁C₇C₄ = 108.0°. For 2,3-diazabicyclo[2.2.2]oct-2-ene, C_2vsymmetry was assumed. The geometrical parameters are: N₃ = N₂ = 1.243 Å, N₃-C₄ = 1.473 Å, C₄-C₅ = 1.550 Å, C₅-C₆ = 1.516 Å, C-H_(ave.) = 1.119 Å,< C₁N₂N₃ = 115.1°, < N₃C₄C₅ = 109.1°, < C₆C₁C₄ = 71.6°.

Crystal and molecular structure of 1-phenyl-2-nitroguanidine

The molecular structure of 1-phenyl-2-nitroguanidine is nonplanar, but contains two almost planar fragments: nitroguanyl and phenyl groups. Unlike previously studied nitroguanidines, in 1-phenyl-2-nitroguanidine, the nitro group is turned to the secondary amino group. However, the structural parameters of the nitroguanyl group are little different from those of nitroguanidine and its alkyl derivatives. In the benzene ring, the symmetry in the geometric parameters is not observed, which is explained by the intermolecular interaction with the neighboring molecule.
