셀레늄(I) 브로마이드

Dark red, almost black, oily liquid with an unpleasant odour; hygroscopic; rapidly liberates Br2 in air, simultaneously separating Se. Partially decomposed on heating; first, some Br2 escapes, then some SeBr4 sublimes, and between 225 and 230°C, a part of the Se2Br2 boils without decomposition, leaving a residue of Se. In water, Se2Br2 sinks to the bottom in oily drops and gradually decomposes into Se, SeO2 and HBr, soluble in CS2 and CHCl3.
