Ammine Complexes

Two cobalt(III) ammine complexes are described which have an imidazolate ( Im ) ligand bridging cobalt(III) centres . Their electronic absorption spectra, 1H, 13C and 59Co n.m.r . spectra, and electrochemical data are presented. One complex is a bis [ pentaamminecobalt (III)] complex, [(H3N)5Co( Im )Co(NH3)5]5+, and the other has two pentaammineimidazolatocobalt (III) units coordinated in the cis arrangement to tetraamminecobalt (III). The crystal structure of cis - [(NH3)4Co{( Im )Co(NH3)5}2]Cl2(S2O6)2(OH).3.5H2O is reported. The crystals in the form of orange needles are monoclinic: Cc, a 20.18(1), b 17.089(9), c 15.395(7) Ǻ, β 123.76(4)°, Z 4. The structure was refined to R 0.079.
