Darstellung gemischter Kaliumhexabromochloro-osmate(IV), K2OsBrnCl6–n (n = 1…5) und Kaliumhexabromochloro-rhenate(IV), K2ReBrnCl6–n (n = 1…5)

Preparation of Mixed Potassium Hexabromochloro Osmates(IV), K₂OsBr_nCl_6–n (n = 1…5), and Potassium Hexabromochloro Rhenates(IV), K₂ReBr_nCl_6–n (n = 1…5) Solutions of mixed hexabromochloro osmates and rhenates which were separated by ion column chromatography are extracted by tridodecylamine in ether. The potassium salts are precipitated from the extractions with potassium acetate and following further purification are characterized spectrophotometrically and by powder X-ray methods.
