✦ Synopsis

Three new cobalt(III) coordination complexes with bidentate amine N-oxide hgands have been synthesized and chumcterized via elemental analyses, equivalent weight determination, molar conductance and magnetic susceptibility measurements, and in@ red and electronic absorption spectroscopy. Two are ionic complexes with general formula [CoL,] (ClO,), where L = 2,2'-bipyridine-Nfl'dioxide and 1 ,I Ophenanthroline N-oxide. The third is a neutral CoL$ complex where L' = picolinate N-oxide. i%e compounds are six-coordinate, diamagnetic, and have electronic absorption spectm typical of the strong field 8 configuration of trivalent cobalt. The perchlorate groups are not coordinated in the solid state or in solution.
