Oxidation of elemental palladium ;at elevated temperatures leads to the blue disulfate Pd(S 2 O 7 ), which has an octahedral and not the usual square‐planar coordination of a Pd 2+ center. In their Communication on page 2204 ff., M. S. Wickleder, R. Pöttgen, and co‐workers show that this rare coordination leads to paramagnetic behavior and that ferromagnetic ordering occurs at low temperature. This is the first example for this phenomenon in an oxidic Pd 2+ compound.
