Palladium dimethylglyoxime (Pd(DMG)2) is a yellow salt insoluble in water. It is formed as a precipitate when mixing palladium salts (for example palladium chloride or palladium nitrate) with dimethylglyoxime. It's chemical formula is Pd(CH3C(NOH)C(NOH)CH3)2 and contains 31% by weight of palladium.
On GRF Freechemist recommended calcination followed by dissolving of the palladium metal sponge by HCl + H2O2 to avoid boil-over and forming nasty organic molecules. It also leaves the Pd in a known 2+ oxidation state.
