Abstract

A series of new intercalation compounds of the layered lanthanide oxychlorides, LnOC1 (Ln = Ho, Er, Tm and Yb), with pyridine has been successfully obtained at both room and high temperature (85 °C). The intercalated pyridine stoichiometries (χ) in the (py)xLnOCl compounds, determined by thermal gravimetric analysis, are independent of the reaction temperature and time after 2 weeks with the (py)xErOCl and (py)xYbOCl, but are affected by the reaction temperature and time with the (py)xHoOCl and (py)xTmOCl. An average interlayer expansion of ∼5 å between the LnOCl layers upon pyridine intercalation suggests that the pyridine ring is oriented perpendicular to the host layers. The pyridine species inserted between the host layers are neutral pyridine molecules. The presence of water in pyridine leads to the pyridinium ion that also intercalates and has been identified by IR spectroscopy.
