Zn(II) and Pd(II) Complexes of Thiosemicarbazone‐S‐alkyl Esters Derived from 2/3‐Formylpyridine

Abstract

Representative S‐methyl/ethyl‐4‐H/phenylthiosemicarbazones and their Zn(II) and Pd(II) complexes were synthesized. Characterization of the 1:1 complexes, [Zn(L)Cl₂], [Pd(L)Cl₂], and [Pd(L)Cl]Cl, was accomplished by means of elemental analyses, IR and ¹H NMR spectra. The multidentate S‐alkyl thiosemicarbazones coordinate as mono‐, bi‐, or tridentate ligands depending on the types of the alkyl moiety and metal ion.

Keywords:

• Polydentate thiosemicarbazones
• Zn(II) and Pd(II) complexes
