Abstract

The SmSI structure type of YbOCl (hexagonal, a = 3.726 (1) Å, c = 27.830 (5) Å) can be intercalated at room temperature with dried pyridine (py) to give the intercalation compound, (py)0.1YbOCl. The presence of H2O in the pyridine leads to the formation of pyH+ and the resulting compound, (H2O)0.7[(py)0.129-x(pyH+) x] YbOCl. Deintercalation of the pyridine occurs at 120°C, whereas that of the pyH+ occurs at 290°C. The X-ray powder diffraction pattern for either compound can be indexed as a 3R structure type with a = 3.7020 (3) Å and c = 42.79 (2) Å. The increase in the interlayer separation of 4.99 Å indicates that the plane of the pyridine molecule is oriented perpendicular to the layers of YbOCl. Intercalation of 4-ethylpyridine shows an increase in the interlayer separation of ∼7 Å, indicating that the lone pair on the nitrogen and the plane of the molecule is oriented perpendicular to the layers. Infrared spectroscopy supports the conclusion that there is coordination of pyridine to the YbOCl host through the nitrogen. The intercalation reaction is described as an acid-base reaction.
