• Pd-II complex

A proton transfer compound L, (MetH)(2)(dipic), (dipicH(2) = 2,6-pyridinedicarboxylic acid and Met = Metformin (N,N-dimethylebiguanidine), was synthesized and characterized by IR, H-1 and C-13 NMR spectroscopy. The reaction of L with PdCl2 in water results in the formation of novel tetracoordinated Pd-II complex [Pd(dipic)(Met)]center dot 2H(2)O indicating the participation of both dipic(2-) and Met as chelating ligands. This complex was characterized by single crystal X-ray analysis. The crystal system is monoclinic with space group P2(1)/c. The unit cell dimensions for Pd-II complex 1 is a = 8.8619(14) angstrom, b = 9.5072(9) angstrom, c = 19.153(3) angstrom.
