Figure 3.
Molecular structures of Cq and Ciq. X-ray structure of Cq: (A) ellipsoid side view, (B) tube side view, and (C) tube top view showing paddle-like array of quinoline panels over palladium(II) center. Solvent molecules and counterions have been omitted for clarity. Ellipsoids are shown at 50% probability. DFT optimized (BP86 def2-SVP) model of Ciq; (D) side view and (E) top view showing lantern-shaped structure. Colors: carbon gray, nitrogen blue, palladium magenta, hydrogen white.
