Synthesis and Characterization of cis-dioxomolybdenum (VI) Schiff base Complexes Derived from S–methyldithiocarbazates, S–benzyldithiocarbazates, 2–aminoethanethiol and –diketones

Abstract

The synthesis and characterization of some cis-dioxomolybdenum (VI) complexes with Schiff base ligands (H₂L) derived from b-diketones and amines such as S–methyldithiocarbazate, S–benzyldithiocarbazate and 2–aminoethanethiol are reported. These complexes were characterized by elemental analyses, molar conductance, IR, UV-Vis, ¹H NMR, AAS, and TGA. The spectroscopic and other analytical data reveal that these Schiff bases behave as dibasic tridentate O,N,S donor ligands and react with [MoO₂(acac)₂] in 1:1 ratio to give diamagnetic mononuclear complexes having the general formula [MoO₂(L)(EtOH)].
