Schiff bases derived from 4,4'-diaminodiphenylsulphone with salicyladehyde and 2-hydroxy-1-naphthaldehyde behave as ON-x-NO donor doubly-bidentate ligands and form dinuclear complexes with divalent Co, Ni, Cu, Zn, Cd and Hg ions. The CoII NiII and CuII complexes are found to be either octahedral or distorted-octahedral, whereas a tetradedral stereochemistry can be assigned to the ZnII, CdII and HgII complexes. The complexes have been characterised by analytical, conductance, magnetic, ir, electronic, esr and nmr spectral data.
