The synthesis and crystal structures of bis-N-(2,5-dimethoxyphenyl)pyridine-2,6-dicarbothioamide (dicarbothioamide I) and 6-(4,7-dimethoxy-2-benzothiazolyl)-N-(2,5-dimethoxyphenyl)-2-pyridinecarbothioamide (L1) as well as the syntheses of the palladium(II) chloride and acetate pincer complexes are reported. The stability constant for the palladium complex formation at 25°C was found to be (2.04 ± 0.26) × 104 dm3 mol-1 and (2.30 ± 0.19) × 104 dm3 mol-1 with ΔfH = 8 ± 1 kJ mol-1, ΔfSθ = 108 ± 10 J K-1 mol-1, and ΔfH = 17 ± 4 kJmol-1 and ΔfSθ = 140 ± 20 JK-1mol-1 for the PdClL1 and Pd(OAc)L1, respectively. The kinetics of formation of the palladium(II) complexes were investigated and the mechanism is proposed to be associative in nature (ΔH‡1 = 34 ± 2 kJ mol-1 and AS‡1 = -113 ± 8JK-1 mol-1, and ΔH‡1 = 37 ± 3 kJ mol-1 and ΔS‡1 = -100 ± 8 JK-1mol-1 for the PdClL1 and Pd(OAc)L1 species, respectively). The electrochemical measurements of the acetonitrile solutions revealed irreversible electron transfers consistent with the electrochemical decomposition of the ligand and its coordination complexes.
