Studies on Reactivity of Homo and Heterobimetallic Thiocyanate Bridged Lewis Acid with Schiff Base Derived from 1,2-Diaminopropane with Salicylaldehyde

Abstract

New complexes of MM(SCN)4 (M = Co²⁺, Ni²⁺, M´= Cd²⁺, Hg²⁺) with Schiff base derived from 1,2-diaminopropane with salicylaldehyde, have been synthesized and characterized by elemental analyses, molar conductance, magnetic moment, FTIR, electronic and ¹H-NMR spectral studies. The softness parameters, ΔTE^≠_n of complexes have also been calculated to derive the probable structures. The complexes have also been investigated for insecticidal activity against red cotton bug (Dysdercus koenigii).
