Abstract

The structure of the lithium inserted rutile-based compound LiMoO₂ has been determined from neutron powder diffraction data by use of the Rietveld profile technique. The inserted Li is incorporated into the MoO₂ lattice in octahedral sites with an average Li0 distance of 2.12 Å. The Mo atoms also occupy octahedral sites with an average MoO distance of 2.12 Ǎ, and form Mo-Mo pairs with a separation of 2.46 Å. LiMoO₂ can best be regarded as having a distorted NiAs-type structure rather than one of rutile-type. No changes in structure were observed in the temperature range 4-400K.
