Moreover, the HsalBH ligand behaves as tridentate anion with all metal ions and an octahedral structure for these complexes is proposed. The three ligands and some of their complexes were screened against three species of bacteria, namely B. cereus (G +ve), P. aeruginosa (G −ve), and S. aureus (G +ve) and five types of fungi, A. flavus, A. fumigatus var. albus, A. niger, F. oxysporum or C. tropicum. The HsalBH ligand has shown high activity against bacteria and fungi, probably due to the presence of a hydroxyl group in this ligand.","PeriodicalId":22160,"journal":{"name":"Synthesis and Reactivity in Inorganic and Metal-organic Chemistry","volume":"4 1","pages":"743 - 762"},"PeriodicalIF":0.0,"publicationDate":"2004-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79848712","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The structure of the lanthanum(III) complex has been determined by x‐ray single crystal diffraction. The lanthanum(III) ion is coordinated through the four nitrogen and the four oxygen atoms of the two ligands to form an eight‐coordinate configuration.
