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

S. Bernès, S. Trujillo Tovar and M. A. Castellanos R

Synopsis: A comparison between the Rietveld and single-crystal X-ray structures of trilithium antimony tetraoxide, Li3SbO4, shows that the first method can yield a poor description of the structure, while the second gives more accurate geometric parameters.

Formula: Li3SbO4

Na3Co(NO2)6 at 293 and 10 K

B. N. Figgis and A. N. Sobolev

Synopsis: Precise X-ray structural determinations of Na3Co(NO2)6 at 293 and at 10 K have been performed. The CoN6 core is quite close to octahedral in stereochemistry. The accurate and extensive data sets collected should be suitable for charge-density analysis studies.

Formula: Na3Co(NO2)6 at 293 and 10 K
