Trapped in a noble cube: A novel family of noble metalates has been discovered in which a 3d metal ion M (M=MnII, FeIII, CoII, CuII, ZnII) is encapsulated by a 12 palladium–oxo cage {Pd12O32}, which is capped by eight phosphate groups. Such discrete nanocubes were further investigated by EPR spectroscopy, electrochemistry, and in homogeneous hydrogenation catalysis.
