Abstract: Mixed ligand complexes of cis-dichloroethionineplatinum (II) and cis-dichloroethioninepalladium (II) with pyrimidines, viz 2-hydroxypyrimidines hydrochloride, isocytosine, 2-mercaptopyrimidine, 5-aminouracil, 2-thiocytosine, and 2-thiouracil have been synthesised and characterised by elemental analysis, conductivity data, IR, UV, 1H and 13C NMR spectra. Based on the spectral data it is found that ethionine coordinates to the metal ion through sulphur and amino nitrogen, leaving a free carboxylic acid group. 2-Hydroxypyrimidine hydrochloride, isocytosine, 2-mercaptopyrimidine act as monodentate ligands and bind to Pt(ll) and Pd(ll) through N3, while 5-aminouracil coordinates to the metal ion through the amino (NH2) group. The 2-thiocytosine and 2-thiouracil however act as bidentate ligands, coordinating to the metal ion through ring nitrogen (N3) and sulphur.
