Structural Features of MoO2-Complexes of Thiosemicarbazones and Semicarbazones

Abstract

Synthesis, characterization and spectral features of six-co-ordinated dioxomolybdenum (VI) complexes of the type (where represents the thiosemicarbazone and semicarbazone moiety, X - O or S) are reported. These have been characterized by elemental analysis, conductance measurements, molecular weight determinations and magnetic studies. Based on IR, ¹HNMR, ¹³CNMR and electronic spectral studies, an octahedral geometry with as –MoO₂ structure has been proposed. The antibacterial and antifungicidal activities of two representative ligands and their dioxomolybdenum complexes have also been evaluated and discussed.
