A proton transfer compound (2a4mpH)2(btcH2) was obtained by the reaction of benzene-1,2,4,5-tetracarboxylic acid (btcH4) with 2-amino-4-methyl pyridine (2a4mp), 1:1 mole ratio and is characterized by IR spectroscopy and single crystal X-ray diffraction analysis. The ion pair is crystallized in monoclinic system and P21/c space group with following cell parameters: a = 11.321(2) Å, b = 13.553(2)...

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 Pī and one molecule per unit cell. The unit cell dimensions are a = 6.9...
