New palladium(II) complexes, [Pd(HL)Cl] · H2O (I) and {K[Pd(L1)(NO2)] · H2O}2, with S-methylisothiosemicarbazone of salicylaldehyde (H2L) and its derivative (H2L1) were synthesized. X-ray diffraction analysis demonstrated the ambident nature of S-alkylated thiosemicarbazone, which is attached to palladium(II) through O, N, and S donor atoms in I and through O, N, and N atoms in II. This is the first known case of metal coordination of the alkylated sulfur atom of a thiosemicarbazide moiety of the ligand. A mechanism of nitrosation of the terminal amide nitrogen atom of the H2L1 ligand during complexation was proposed.
