Abstract

New mixed nitro-complexes of cobalt(III) have been obtained by substitution reactions from Na₃[Co(NO₂)₆] and by various anation reactions from [Co(Niox.H)₂(H₂O)(NO₂)] with halides (Cl-, Br-), pseudohalides (CN-,NCX-; X=O,S,Se) and with aromatic and heterocyclic amines, respectively. A series of binary salts of the type Cation [Co(Niox.H)₂(H₂O)(NO₂)Y] )Y] (Y=halide or pseudohalide) and nonelectrolytes [Co(Niox.H)₂(H₂O)(NO₂) (aminel] have been isolated and characterized.(Niox.H₂ - nyoxime - 1,2-cyclohexane dione dioxime). Some structural problems are discussed on the basis of UV and IR spectra.
