The reaction of 3-formylsalicylic acid with morpholine N-thiohydrazide produces 3-carboxy-2-hydroxybenzaldehyde morpholine N-thiohydrazone (H2chbmth) which remains in equilibrium in solution with its corresponding thiol form H3chbmthol having an NSO donor set of atoms. The reactions of the thiohydrazone ligand with different organometallic compounds viz. R2MCl2 (R = π-C5H5 & M = Ti/Zr; R = Me/Ph & M = Sn; R = OMe & M = Sn), (π-C5H5)2Ti(OMe)Cl2 and RMCl3 (R = Me/Ph & M = Sn; R = π-C5H5 & M = Ti) leading to the syntheses of many new organometallic derivatives have been studied. In all of the complexes the dianion of the H3chbmthol ligand functions as a dibasic tridentate NSO donor. The reactions of [(π-C5H5)Ti(Hchbmthol)Cl] and [MeSn(Hchbmthol)Cl], isolated in this study, with Me3SiE (where, E stands for NMe2 and C≡CPh) and MeSH have also been studied and many new organoderivatives of these two metal ions isolated. All the compounds under study have been characterized by elemental analyses, magnetic susceptibilities, molar conductance values, molecular weights and spectroscopic (UV-Vis, IR, 1H NMR) data. Based upon these data the geometry of the compounds has also been proposed. |
