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.

The synthesis and characterization of Ti and TiN thin films of different thicknesses was carried out on a martensitic stainless steel AISI 410 substrate used for tool manufacturing. The mechanical parameters between the interacting surfaces such as thickness, adhesion and hardness were measured. By means of the scanning electron microscope (SEM) the superficial morphology of the Ti/TiN interface was observed, finding that the growth was of columnar grains and by means of EDAX the existence of titanium was verified.  Using X-ray diffraction (XRD) it was possible to observe the presence of residual stresses (~ -3.1 GPa) due to the different crystalline phases in the coating. Under X-ray photoemission spectroscopy (XPS) it was possible to observe the molecular chemical composition of the coating surface, being Ti-N, Ti-N-O and Ti-O the predominant ones.
