A series or new Cu^II and Ni^II binuclear complexes of Schiff base N,N'-ethylencbis(2-hydroxyacetophenonimine) (EA) with some organic derivatives or alkaline earth metals or general formula M_aEA.M_bL₂, where M_a = Cu or Ni; M_b = Mg, Ca, Sr or Ba; L= deprotonated o-nitrophenol (ONP), 2,4-dinitrophenol (DNP), 2,4,6-trinilrophenol (TNP), 1-nitroso-2-naphthol (1N2N) have been synthesized. The nature of bonding and stereochemistry or the complexes have been deduced by elemental analysis, infrared spectra, electronic spectra, magnetic susceptibility and conductivity measurements. The compounds are tested against Gram +ve bacteria (S. aureus), Gram -ve bacteria (E. coli) and fungi (C. albicans).
