Metal complexes of triazole-2-yl thiourea: synthesis, characterization and equilibrium studies

ABSTRACT

Triazoles have been reported to be biologically versatile compounds, having bactericidal[1], fungicidal [2] insecticidal[3] and pesticidal[4]properties, also thiourea. Frequently display a wide biocidal activities [5,6]. It is well known that certain metal complexes have greater activity than the coordinating agents themselves [7] This has led us to study in the present work a new thiourea derivative having a triazole moiety with some transition metal ions, in continuation to previous studies on thiourea complexes[8]. The present investigation comprises l-triazole-2-yl-3-benzoyl- thiourea, BTu, and some of its metal complexes. The composition and structure of the formed complexes have been characterized by elemental analysis, potentiometric titrations, electrolyte conductance, IR, electronic and proton NMR spectrometry and magnetic susceptibility measurements
