Crystal Structure of Bis (2,6-diaminopyridinium) tetrachloro palladate(II) of a Pyridine Containing Self- Assembling System

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[PdCl4]. The crystal structure of the compound was determined by X–ray diffraction. The crystal system is triclinic with space group P < /em>ī and one molecule per unit cell. The unit cell dimensions are a = 6.900(3) Å, b  = 7.898(3) Å, c = 8.025 (3) Å, with α = 103.302(14)º, β  = 104.068(14)º and γ = 92.415(12)º. The final R value is 0.0602 for 1988 reflections. The presumably of the formation [pyda.H][Pd(pydc)(pydc.H)], [Pd(pydc.H)2] and [pyda.H]Cl species, was studied by IR, ESI/MS, 1H NMR, 13C NMR spectroscopy, and elemental analysis.
