Abstract
The equilibrium molecular structure of 1,1\textit{'},6,6\textit{'}-tetraaza-7,7\textit{'}-bi(bicyclo[4.1.0]heptane) in the gas phase has been determined from the data of the gas phase electron diffraction method using quantum chemical calculations up to the RI-MP2/def2-QZVPP level of theory. Structure studies were also carried out in $\mathrm{CDCl_3}$ solution using 1D and 2D $\mathrm{^{1}H}$ and $\mathrm{^{13}C}$ NMR spectroscopy and in the solid state using X-ray diffraction analysis. In the gas phase, three conformers of the molecule have been identified, while only one conformer is present in the $\mathrm{CDCl_3}$ solution and in the solid state, in which the substance crystallizes in space group $P\overline{1}$.
