Figure 6
(a) The structure of compound 9, including selected bond lengths (in Ångstroms; given as one less significant figure than in the CIF for clarity), as determined by X-ray analysis, and (in brackets) via geometry optimization in vacuo at the B3LYP/6-311G(d,p) level of theory. (b) Stereoscopic view of the structure of compound 9, as determined by X-ray diffraction. (c) Two views of the octa­aza­cyclo­decane backbone of compound 9, in which atoms other than those that define the ring have been hidden from view (N atoms blue and C atoms gray). Viewpoint I is from the top of the ring system. Viewpoint II is from the side, where the two C atoms within the ring system are eclipsed. Displacement ellipsoid plots are provided in the supporting information.
