Abstract
Osmium complexes of the type [OsB2X2]n+ where B = 2,2'-bipyridine (bipy) or 1,10-phenanthroline (phen), X = Cl, Br, I, py, NH3; 2X = glycinato, acetylacetonato, ethylenediamine, oxalato, phen, or bipy and = 0, 1, 2, 3 are described. [OsB2X2]0 has the cis configuration. Usually compounds in both oxidation states (II) and (III) were stable and could be isolated. The compounds did not disproportionate and the unidentate ligands were replaced only with difficulty. The [Osbipy2phen]2+ and [Osbipyphen2]2+ ions were resolved through their (+) antimonyl tartrate salts and were found to be optically stable in both the Os(II) and Os(III) states.Keywords
