N2  - The following cobalt(11) complexes containing the chelate 2,2'-dithiodipyridine (&#945;dtp) and the isomeric chelate 4,4'-dithiodipyridine (&#947;dtp)* have been prepared and investigated: Co(&#945;dtp)X2 (X = Cl, Br,I and NCS), Co(&#947;dtp)Cl2 and Co(&#947;dtp)2X2 (X = I and NCS). All, except the first three, are described for the first time. Physicochemical investigations indicate that the complexes Co(&#945;dtp)X2 (X = Cl,Br and I) are tetrahedral monomers and Co(&#945;dtp)(NCS)2 is an octahedral polymer. Co(&#947;dtp)Cl2, appears to be tetrahedral whereas Co(&#947;dtp)2X2 (X = I and NCS) are octahedral polymers. Although the complete interpretation of the spectra is rendered difficult by the ligand bands occurring at lowfrequencies, far-infrared spectra have provided evidence that both nitrogen atoms in &#945;dtp and &#947;dtp are coordinated in these complexes.
