Six bicadmium(Ⅱ) cryptates[Cd2Ln] were synthesized by the[2+3] Schiff base condensation of 2-aminoethyl-bi(3-aminopropyl) amine with sodium 2,6-diformyl-4-R-phenolate(R=CH3,CH3O,(C(CH3)3,F,Cl,Br,n=1,2,3,4,5,6,respectively) in the presence of Cd2+.After one imine group of[Cd2L1] was hydrolyzed and solvent addition,with no ring opening,cryptate[Cd2Lh] was produced.The structures of the seven complexes were confirmed by elemental analysis,IR,electronic spectrum,and ES-MS.The toxicities of the complexes were evaluated by testing antimicrobial activity against bacterial strains.The complexes were active against four organisms tested with no exception,showing highest antimicrobial activity against staphyloccus aureus.
