Abstract

A new potassium palladate KPd2O3 was synthesized by the reaction of KO2 and PdO at elevated oxygen pressure. Its crystal structure was solved from powder X-ray diffraction data in the space group R 3m (a=6.0730(1) Å, c=18.7770(7) Å, and Z=6). KPd2O 3 represents a new structure type, consisting of an alternating sequence of K+ and Pd2O3-layers with ordered Pd2+ and Pd4+ ions. The presence of palladium ions in di-and tetravalent low-spin states was confirmed by magnetic susceptibility measurements.
