Effects of the nearest-neighbor environment of copper atoms on the XANES spectra of layered chromium-copper disulfides

In the present work, the K absorption spectra of copper, chromium, and vanadium of layered chromiumcopper disulfides CuCr1–x V x S2 (x = 0–0.4) are studied. Based on the comparison of the experimental and theoretical spectra obtained by simulation with the FDMNES program package, it is shown that copper atoms occupy tetrahedral sites, and chromium atoms and substitutional vanadium atoms occupy octahedral sites in the whole set of the samples studied.
