“…Taking into consideration the previous reports [37] we have attributed a band of medium intensity appearing around 290 cm -1 to ν(Zr-Cl) vibration. The appearing of only one medium intensity band in the above region makes us to corroborate that chlorine atoms in the complex occupy the Trans position.…”

Novel tridentate Schiff base ligand derived from the 2-aminobenzenthiol and 8-hydroxy-7-quinolinecarboxaldehyde (oxine) and its metal complexes have been prepared. The reaction of a solution of 7-(2,3-dihydro-1,3-benzothiazol-2-yl)quinolin-8-ol (H 2 L) with di-and tetravalent transition metals have been studied chemically and biologically. The optimized bond lengths, bond angles and calculated the quantum chemical parameters for the ligand (H 2 L) [the cyclic form (A) and the Schiff base form (B)] were investigated. The complexes have been characterized by elemental analyses, IR spectra, thermal analyses and 1 H-NMR spectroscopy. The spectral studies of the isolated complexes showed that the rearrangement of the benzothiazoline to the Schiff base had occurred. The data suggest that the Co(II) and Ni(II) complexes are binuclear and octahedral dimmers, while the rest are monomeric with square planar/ tetrahedral geometries. The ESR spectrum of the Cu(II) complex show axial type symmetry with g ll >g┴>2.002, indicating d x2-y2 ground state with significant covalent bond character. Five doses were topically applied against the newly emerged adults of the red palm weevil Rhynchophorus ferrugineus. Percent of adult mortality was 98.2%, which occurred after adult treatment with the highest dose (2.2 mg/ml) of Ni(II) complex. The lowest mortality was 5.6% which obtained due to effect of oxine after adult was treated with dose of 0.25 mg/ml. Five doses were topically applied against the newly emerged adults of the stored product weevil, Sitophilus granaria. While the lower mortality, 5% caused due to effect of least dose, 0.15 mg/ml of the compound oxine.

The reactions of a few bifunctional and tridentate Schiff bases with titanium‐(IV) and zirconium(IV) isopropoxides in equimolar and bimolar ratios are described. The resulting compounds have been obtained in almost quantitative yields and are of the general formulae M(SB)x(OPri)4−2X (where M = Ti or Zr; SB‐ = anion of the Schiff base SBH2 and x = 1 or 2). Their molecular weights have been determined ebullioscopically and IR spectra recorded.
