The structure of Li3Cu2O4, a compound with formal mixed valence
1993 (English)In: J Alloys Comp, Vol. 190, 295-299 p.Article in journal (Refereed) Published
The structure of Li3Cu2O4 was solved from X-ray powder diffraction data and refined from a multiphase specimen using the Rietveld method. The cuprate crystallizes in C2/m with Z=2. The compound has a small homogeneity range. Typical parameters are a= 9.946(5) Angstrom, b= 2.778(2) Angstrom, c= 7.260(5) Angstrom and beta= 119.10(2) degrees. The structure may be described as an ordered intergrowth of slabs of Li2CuO2 and hypothetical LiCuO2 of NaCuO2 type. The formula suggests a copper (II,III) mixture, but there is only one crystallographic copper site
