The solution was chilled in a freezing mixture, the crystals filtered with slight suction on a cold Biichner funnel with paper and the filtrate added to the next preparation; yield, 90-95%. It may contain dithiocyanate, from which it can be freed by sublimation; mp 76.1-76.6'; bp 127" (corr.) (by the Siwolliboff capillary tube method); sulfur, 27.57,; calcd., 27.6%.
