Synthesis and Characterization of the Dicopper(II)‐Containing 22‐Palladate(II)[Cu^II₂Pd^II₂₂P^V₁₂O₆₀(OH)₈]²⁰⁻

A couple of coppers: Two CuII ions exhibit highly distorted cubic coordination and unexpectedly large magnetic exchange coupling in a discrete dicopper(II)-containing 22-palladate(II). The compound is isolated as the hydrated sodium salt Na20[CuII2PdII22PV12O60(OH)8]⋅58 H2O (1) in which the polyanion (see structure: Cu turquoise, Pd blue, O red balls, {PO4} purple tetrahedra) is the largest noble metalate reported to date.
