in water a mixture of NaHC2O4 and oxalic acid with the 3 - 4 fold amount of H2O is refluxed for 60 h; product pptd. on cooling;; the crystals are heated in their mother liquor with little OsO4 until the smell of OsO4 disappears; pure crystals are pptd. when soln. is cooled down; a second fraction is isolated from mother liquor after pptng. H2C2O4 with CaCl2;;
