Abstract
The structures of five perovskite-related oxides with the general composition ACu3Ru4O12 with A=Na, Ca, Sr, La and Nd, have been examined both by XRD-Rietveld refinements and Ru-K EXAFS-spectroscopy. In addition, the behavior on reduction was investigated by thermogravimetry (TG). The TG measurements revealed that the composition was almost exactly A1Cu3Ru4O12 for all samples. The inter-atomic distances derived from EXAFS- and XRD-Rietveld fits show an excellent agreement with differences smaller than 8 m? even for R>5 ?. All inter-atomic distances increase in the order Na
