The pyrazolyl group has been used in conjuction with the amido group for the design and synthesis of a new series of bifunctional ligands, PzCH2C(O)NHR, where Pz = 1-pyrazolyl 3,5-dimethyl-1-pyrazolyl; R = H(APz/ADMPz), Me(MAPz/MADMPz), Ph(PAPz/PADMPz). These ligands have been characterized based on their mass, IR, 1H and 13C{H} NMR spectra and their complexes with PdII and PtII reported. Simple mixing of aqueous solutions of K2[MCl4] (M = Pd. Pt) and the pyrazole amide in a 1:2 ratio gave neutral complexes of the type cis-MCl2L2;. Alternatively, an aqueous solution of K2[MCl4] added to an aqueous solution of ligand at pH - 8.0 afforded neutral bis-chelates of the type ML2. A neutral monodentate coordination (LH) has been assigned for the ligand in the former complexes, whereas uninegative bidentate coordination through deprotonated amide nitrogen has been assigned in the latter complexes.
