Rotational, centrifugal distortion and quadrupole (<jats:sup>35</jats:sup>Cl, <jats:sup>37</jats:sup>Cl, <jats:sup>14</jats:sup>N) coupling constants have been precisely obtained. The two subunits of the complex are held together via a Cl⋅⋅⋅N halogen bond interaction. Information on the internal dynamics and on the dissociation energy of the complex is provided.</jats:p>
