Two novel, stable Pd-II complexes, compounds 3 and 4, of two 3-hydroxypyridine-2-carbaldehyde thiosemicarbazones, 1 and 2, resp., were prepared from Li2PdCl4. The single-crystal X-ray structure of complex 3 (=[Pd(2)Cl]) shows that the ligand monoanion coordinates in a planar conformation to the metal via the pyridyl N-, the imine N-, and the thiolato S-atoms. Intermolecular H-bonds, pi-pi, and CH...pi interactions lead to a two-dimensional supramolecular assembly. The electronic, IR, UV/VIS, and NMR spectroscopic data of the two complexes are reported, together with their electrochemical properties. A sophisticated experimental procedure was used to determine the multiple dissociation constants of the ligands 1 and 2 by UV/VIS titration. (EN)
