Abstract: 

The reaction between LH2, [pyda.H2] [pydc], (pyda = 2, 6 - pyridinediamine and pydc. H2 = 2, 6 - pyridinedicarboxylic acid), ligand with palladium (II) chloride leads to the formation of  [pyda.H]2 [PdCI4]. The crystal structure of the compound was determined by X-ray diffraction. The crystal system is triclinic with space group Pī and one molecule per unit cell. The unit cell dimensions are a = 6.900(3) Ǻ, b = 7.898(3) Ǻ, c = 8.025 (3) Ǻ, with α = 103.302(14) °, β = 104.068(14)° and γ= 92.415(12)°.The final R value is 0.0602 for 1988 reflections. The  resumably of the formation [pyda.H][Pd(pydc)(pydc.H)], [Pd(pydc.H)2] and [pyda.H]CI species, was studied by IR, ESI/MS, 1H NMR, 13C NMR spectroscopy, and elemental analysis.
