Complexes of platinum(II) and palladium(II) with N-(2-methyl-4-aminopyrimidinyl-5)methylaniline

Abstract

The reactions of K 2MX 4, where M = Pt(II), Pd(II) and X = Cl, with thiamine derivative, L, N-(2-methyl- 4-aminopyrimidinyl-5)methylaniline have been studied in aqueous medium (1:2 molar ratio). The products of the general formula MLX 2 have been isolated and characterized by elemental analyses, infrared, proton and carbon-13 nuclear magnetic resonance spectra. A complete assignment of 1H and 13C NMR spectra resonances for both the free ligand and its metal complexes is presented for the first time. The results show that this ligand behaves like a bidentate ligand, coordinating through either the exocyclic amino group and the side chain nitrogen donor atom or the endocyclic nitrogens, N-1′ and N′-3′.
