Synthesis, characterization and antifungal studies of metalloquinolone [Cd2(nal)2(phen)2(Cl)2]

Abstract

A novel dinuclear, distorted octahedral complex of nalidixic acid (nal) with Cd(II) metal ion with the formula [Cd2(Nal)2(Phen)2(Cl)2] has been synthesized in the presence of N-containing heterocyclic ligand, 1,10-phenanthroline (phen). The synthesized metal complex was characterized using CHN analysis, Fourier transformed infra-red, thermo gravimetric analysis, differential scanning chalorimetry, nuclear magnetic resonance, ultra violet-visible and single-crystal X-ray diffraction. The newly synthesized complex shows more pronounced antifungal activity compared with the parent quinolone against four fungi, namely Pythium aphanidermatum, Sclerotinia rolfsii, Rhizoctonia solani and Rhizoctonia bataticola.
