“ SYNTHESIS AND SPECTRAL STUDIES OF MIXED LIGAND COMPLEXES OF FE(III) WITH BENZOYLACETONE AND SALICYLALDEHYDE, SUBSTITUTED SALICYLALDEHYDES, 2-HYDROXY- ARYL CARBONYL COMPOUNDS OR Â-DIKETONES”

Mixed ligand complexes of Fe(III) of the type and [Fe(bzac) L], where bzac is
benzoylacetone and HL is substituted salicylaldehyde, â-Diketones or hydroxylaryl
ketones have been synthesized by the condensation reactions of Iron (III) chloride with
a mixture of two different ligands in 1:2:1 molar ratios. The solid complexes were
separated, filtered, washed with ethanol and ether successively and dried under reduced
pressure. The resulting complexes have been characterized by elemental analyses, molar
conductances, magnetic moments, electronic spectra, IR spectra and FAB mass spectra
analysis. At the same time, above mentioned complexes were studied for in vitro
antimicrobial properties and found to be more potent bactericides than parent ligands.
Octahedral geometry has been proposed for the mixed ligand complexes

本研究合成了通式为[Fe(bzac)L]的三价铁混合配体配合物，其中bzac为苯甲酰丙酮（benzoylacetone），HL为取代水杨醛、β-二酮或羟基芳基酮。该类配合物由三氯化铁与两种不同配体以1:2:1的摩尔比经缩合反应制得。将所得固体配合物分离、过滤，依次用乙醇、乙醚洗涤后减压干燥。通过元素分析、摩尔电导率、磁矩、电子光谱、红外光谱以及快原子轰击（FAB）质谱对上述配合物进行了表征。同时对其开展体外抗菌性能研究，结果显示其杀菌活性优于母体配体。研究提出该类混合配体配合物具有八面体几何构型。
