Illustrations of the intermolecular interactions between p-xylene and oxygen atoms in SL-1. Straight channel (top) and sinusoidal channel (bottom) with arrangements of the p-xylene molecules with carbon atoms shown as 50% probability displacement ellipsoids. The intermolecular distance between independent p-xylene molecules is d(C8⋯Cg) = 3.498 Å where Cg is the center of gravity of the C9–C14 ring. |
