Abstract: The in situ reactions of a mixture of 2, 4-pentanedione and 2-aminobenzenethiol with Ni(II) and Pd(II) salts yield complexes of the type [M2(MPIP)2] where H2MPIP is the schiff base 2-(2-mercaptophenyl)imino- 4-pentanone obtained by condensation of one molecule of the ketone with one molecule of the amine, On the other hand, similar reactions with Co(II), Fe(III) and Cu(II) salts give the complexes [Co(PDMPI), [Fe(PDMPI) CI] and [Cu2(PDMPI)CI2] where H2PDMPI is the schiff base obtained by the condensation of two molecules of the amine with one molecule of the ketone. [Fe(pDMPI)Cl] smoothly reacts with bifunctional alkylating agents like 1, 2-dibromoethane and α, α'-dibromo-o-xylene to form the macrocyclic complexes of {S, S'-ethylene-2, 4-bis(2'- ercaptophenylimino)pentane} iron(III), [Fe(EPDMPI)Cl]Br2 and {S, S'-o--xylyl-2, 4-bis(2' -mercaptophenylimino)pentane} iron (III), [Fe(XPDMPI)CI]Br2 respectively as a result of the alkylation of the two coordinated mercaptide groups of the complex.
