- 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

Tidskriftsartikel (refereegranskat)abstract
- The electronic structure of MnO has been investigated using high-energy spectroscopies. An experimental gap of 3.9 eV is found. By comparing the experimental results to a configuration-interaction cluster model, values for the different parameters in a model Hamiltonian are found.
