dc.description.abstract	<p> The insertion of lithium into the rutile structures RuO 2 and IrO2 was found, by X-ray powder diffraction, to result in the formation of the orthorhombic phases Li0.9RuO2 and Li0.9IrO2, respectively. The orthorhombic cells of the intercalation products are related to the tetragonal transition metal dioxide cells by a large expansion (~ 0.5 Å) in the [100] and [010] directions and a smaller contraction (~ 0.3 Å for Li0.9RuO2 and 0.05 Å for Li0.9IrO2) along the [100] axis. Both LixRuO2 and LixIrO2 are two phased systems over the range of lithium compositions studied (0.2 <~ x <~ 0.9).</p> <p> The structure of Li0.9RuO2 was determined by neutron powder diffraction. The structure adopted by Li0.9RuO2 is a distorted NiAs-type structure quite similar to that of a related compound LiMoO2. Unresolved difficulties were encountered in attempting to prepare samples of LixOsO2 and LixIrO2 suitable for their structure determination.</p>	en_US
