Synthesis, crystal structure and bioactivity of a novel 18-metallacrown-6 [Mn6(H2O)6(abshz)6]·36H2O
摘要:
A novel 18-metallacrown-6 compound, [Mn-6(H2O)(6) (abshZ)(6)] center dot 36H(2)O (abshz = N-acetyl-5-bromosalicylhydrazide), has been prepared and characterized. The crystal structure contains a neutral 18-membered metallacrown ring which is formed by the succession of six structural moieties of the type [Mn(III)-N-N]. Due to the meridional coordination, the ligand enforces the stereochemistry of the Mn3+ ions as a propeller configuration with alternating Lambda/Delta forms. Antibacterial screening data showed that the complex has strong antimicrobial activity against Staphylococcus aureus, Escherichia coli and Bacillus subtilis. (C) 2006 Elsevier B.V.
