摘要：

A neutron powder diffraction study at 5 K of 1,3,5-trimethylbenzene adsorbed in Na, Yb-Y zeolite is reported. The space group is Fd3mBAR with a = 24.6173(5) angstrom. The molecules are located in the supercage, attached to the SII sodium ion. Two distinct sites, that correspond to two different orientations of the molecules with respect to the framework are observed. The distances of the ring centers to the Na+ ions are 2.604(2) angstrom and 2.582(2) angstrom for the molecules on sites A and B, respectively, indicating the formation of pi-complexes.
