Synthesis and properties of potassium tetrabromodioxoosmate(VI)

Full Text:

Abstract

The behaviour of K2[OsO2(OH)4] in solutions with different concentration of HBr was studied by EAS method, chemical forms of osmium were established, the method of synthesis of K2[OsO2Br4] from K2[OsO2(OH)4] was developed. The properties of K2[OsO2Br4] were examined by IRS, EAS and TG methods
