• Resumen

  • The ionic cobalt (II) title complex [Co2(OH)2 (Ac)3(Bipy)2]·K ·2(H2O) (where Ac: Acetate, Bipy: 2,2-bipyridine) consists of anionic bimetallic unit in which cobalt ions are bridged by hydroxo and acetate ligands, balanced by a (disordered) potassium cation. The geometry at cobalt is distorted octahedral with the O atoms of a monodentate and a bridging acetate groups occupying the apical sites and O atoms from the hydroxo groups and N atoms from Bipy, the equatorial sites in each cobalt coordination sphere. Magnetic susceptibility data of powdered samples of the compound are presented. The antimicrobial activities of the complex has been screened in vitro against the microorganisms Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli
