The reactions of ruthenium(II) complexes, [RuHCl(CO)(PPh3)2(B)] [B = PPh3, pyridine (py) or piperidine (pip)], with bidentate Schiff base ligands derived by condensing salicylaldehyde with aniline, o-, m- or p-toluidine have been carried out. The products were characterised by analytical, i.r., electronic, 1H-n.m.r. and 31P-n.m.r. spectral studies and are formulated as [RuCl(CO)(L)(PPh3)(B)] (L = Schiff base anion; B = PPh3, py or pip). An octahedral structure has been tentatively proposed for the new complexes. The Schiff bases and the new complexes were tested in vitro to evaluate their activity against the fungus Aspergillus flavus.

Complexes of 2-mercaptopyrimidin-4-ol with RhIII, PdII, PdIV, PtII and PtIV have been prepared. Their tentative structures have been assigned on the basis of infrared and electronic spectra and magnetic and analytical data. The ligand behaves as a bidentate bridging ligand towards metal ions except for PtII. Crystal field parameters have also been calculated.
