Abstract

Many complexes of Cu, Ag, Au in combination with dianions derived from 2, 5-dihydroxy-1, 4-benzoquinone and 3, 6-dichloro-2, 6-dihydroxy-1, 4-benzoquinones have been synthesized and analysed for their antimicrobial activity. The I.R, 1H and 13CNMR data reveals that 2, 5-dihydroxy-1, 4-benzoquinone, coordinates as an O, O donor of the o-quinone type in cis-Na2[Cu2O5(HBQ)2] 5H2O, cis-(PPh4)2[Cu2O5(HBQ)2], cis-Na2[Ag2O5(HBQ)2]4H2O, trans-AuO2(HBQ).H2O and chloranilate di-anion functions as an O, O ligand in cis-Na2[Cu2O5(DDB)2] 6H2O, cis-(PPh4)2[Cu2O5(DDB)2] 4H2O, cis-Na2[AgO2(DDB)2], cis-(PPh4)2[AgO2(DDB)2] 5H2O, trans-(n-Bu4N)2[AuO2(DDB)2]3H2O. The complexes synthesized showed a good response as antimicrobial agents against the bacterial strains, viz, Bacillus subtilis, Staphylococcus aureus, Xanthomonas malvacearum, E.coli, Rhodococcus sp, Pseudomonas putida.
