Abstract
Rare earth perchlorate complexes of 4-(2'-hydroxynaphthylazo) antipyri ne (H-NAP) of the composition [Ln(NAP)(2)]ClO4 (where Ln = La, Pr, Nd, Sm, Gd, Dy and Y) have been prepared and characterised. In these comp lexes NAP(-) acts as a tridentate ligand and ClO4- is uncoordinated. T hese complexes were screened-for their anti-staphylococcal activity by turbidimetric assay method and were found to be more antibacterial th an the ligand.
