Studies on Benzothiazoline Complexes of Manganese(II)

Abstract

The 1:1 and 1:2 molar reactions between hydrated manganese acetate and the benzothiazolines having the donor group NS have yielded tetra-coordinated manganese(II) Schiff base complexes. The resulting complexes [Mn(Bzt) (CH₃COO)H₂O] and [Mn(Bzt)₂] (where BztH = monofunctional bidentate benzothiazoline) have been characterized on the basis of elemental analysis, molecular weight determinations and conductance and magnetic measurements. The infrared, electronic and electron spin resonance spectral studies indicate a high spin tetrahedral geometry for the resulting complexes. Some of these derivatives have also been screened for their fungicidal activity.
