    • Abstract


      Reaction between 3-formylsalicylic acid and bis-(2-aminophenyl)-disulphide yields a septadentate Schiff base with N2SO4 donor frame of which the inner compartment is N2SO2 and the outer is O2O2 type. It forms several complexes with inner copper centre and outer nontransition/transition metal ions. The complexes have been characterised by elemental analyses, spectral (IR, absorption, diffused reflectance), thermal and magnetic data. Dinuclear copper complexes exhibit subnormal magnetic moments (≈ 0.80 BM), showing magnetic exchange, and six-line solid-state ESR spectra at 77 K.
