“…All the complexes show superior antifungal and antibacterial activity compared to the free ligands and starting ruthenium(III) complexes. Such increase activity of the metal complexes can be explained on the basis of Overtone's concept [44] and Chelation theory [45,46]. According to Overtone's concept of cell permeability, the lipid membrane that surrounds the cell favours the passage of only lipid soluble materials due to which liposolubility has an important factor which controls the antimicrobial activity.…”

A series of new binuclear Ru(III) complexes of the type {[RuX 3 (EPh 3 )] 2 (bis-b-dk)} [X = Cl/Br; E = P/ As bis-b-dk = bis(b-diketone)] have been prepared by reacting [RuCl 3 (PPh 3 ) 3 ], [RuCl 3 (AsPh 3 ) 3 ], [RuBr 3 (PPh 3 ) 3 ],[RuBr 3 (AsPh 3 ) 3 ] with bis(b-diketones) in a 2:1 molar ratio in benzene. These complexes have been characterized by physico-chemical and spectroscopic methods. The redox property of the complexes were studied by cyclic voltammetric technique. The complexes were found to be effective catalysts for the aryl-aryl coupling and oxidation of benzyl alcohol, cyclohexanol, propan-1-ol and 2-methylpropanol to benzaldehyde, cyclohexanone, propionaldehyde and 2-methylpropionaldehyde, respectively, using molecular oxygen as primary oxidant. All the complexes have been screened for their antibacterial and antifungal activities.

“…The increase in biocidal activity of the complexes over that of the ligand may be due to the effect of the metal ion on the normal cell process. A possible mode for increase in biocidal activity may be considered in the light of Overton's concept [54] and the chelation theory [55]. According to Overton's concept of cell permeability, the lipid membrane that surrounds the cell favors the passage of only lipidsoluble materials so that liposolubility is an important factor which controls biocidal activity.…”

The structural and spectroscopic properties of novel five-coordinated dimeric-Cu(II) system have been investigated. The biocidal activities of all eight compounds, ligands, cupric nitrate and standard drugs against six bacteria and three fungi were determined. The DNA interaction activity of complexes was studied using spectrophotometry and electrophoresis. The superoxide dismutase (SOD)-like activity of the complexes was compared with previously reported monomeric-and dimeric copper complexes. The results support the five-coordinated dimeric square pyramidal geometry for the quinolone-Cu(II) system.

“…Since the enolic hydrogen is labile, it can be replaced by a metal cation to form a six-member chelate ring. The β-diketonate complexes thus formed have been the topic of hundreds of papers and reviews [1][2][3][4][5], and widely used in a lot of aspects in industry, such as organic electroluminescent technology, luminescent materials, sensors for bioinorganic applications, luminescent labels in bioaffinity assays [1,2], NMR shift reagents [6][7][8], laser chelates [9,10], extraction agents [11][12][13], heat stabilizers for polymers, drugs [14,15], chemical and photochemical catalysts [16]. Moreover, they are used in manufacturing supra-conductors [17,18] and gas chromatography [19,20].…”

The enol form of ethyl acetoacetate (EAA) displays interesting spectroscopic characteristics; this form of ethyl acetylacetate is very important in condensation reaction. In this investigation, we have studied the interactions and the complex formation constants (K f ) with nano alumina (10-20 nm) particle and alumina (mesh 135) compounds as Lewis acids in the acetonitrile solvent using absorption spectroscopy and related calculations. Furthermore, in this study we calculated the thermodynamic parameters of this reaction. The trend of reactivity of the ethyl acetoacetate (EAA) complexes toward the above Lewis acids, based on the solvent as follows: nano alumina compound > alumina compound.
