A comparison of the X-ray single-crystal structure of Li3SbO4 with the Rietveld refinement

The X-ray single-crystal structure of trilithium antimony tetraoxide, Li3Sb O4, is compared with the Rietveld refinement previously reported for the sa me material. An analysis of the geometric parameters and s.u.'s extracted f rom both refinements shows that, as expected, powder data yield a less accu rate structure. Nevertheless, both refinements give correct geometric param eters within s.u.'s characteristic of each technique.
