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

Abstract

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.
