A 1H NMR spectra (500 MHz, 25 °C, CDCl3/CD3OD 10:1 v/v) of a) [rac-HOMO-2a] = 5 mM, b) [rac-HOMO-2a] = 5 mM with [NC6N] = 5 mM, c) [NC6N] = 10 mM. B Section of the 2D TOCSY spectrum of [rac-HOMO-2a] = 5 mM with [NC6N] = 5 mM. * Asterisks indicate residual solvent peaks. A single enantiomer is shown in the scheme of the complex. C Top-view and side-view stick models and side-view space fill model of the solid-state structure of out-rac-HOMO-2a ⊃ NC6N complex (single enantiomer). In the space-fill model, the host is represented by the color brown and the guest and solvent molecules are represented by the color cyan.
