It's hip not to be square : The oxidation of elemental palladium with SO 3 leads to Pd(S 2 O 7 ) in which the Pd 2+ is in an octahedral coordination environment of oxygen atoms (see structure Pd red, O blue, S yellow) and not the usual square‐planar environment for Pd 2+ species. This unexpected geometry leads to the observed paramagnetism of the compound with ferromagnetic ordering at 11.7 K.
