Abstract
Rare earth perchlorate complexes of 4–(2′−hydroxynaphthylazo) antipyrine (H-NAP) of the composition [Nn(NAP)2]CLO4 (where Ln=La, Pr, Nd, Sm, Gd, Dy and Y) have been prepared and characterised. In these complexes NAP− acts as a tridentate ligand and CLO −4 is uncoordinated. These complexes were screened for their anti-staphylococcal activity by turbidimetric assay method and were found to be more antibacterial than the ligand.
