The complex has been characterized by elemental analyses, magnetic measurements, UV‐VIS and IR spectra. Stability constants and thermodynamic values for complexation between Cu(NO3)2, Zn(NO3)2 · 6H2O, and VOSO4 · 5H2O salts and the ligand synthesized by the method described in the literature in 80% dioxane–water and pure methanol were determined by conductance measurements. The stability constants (log K e) in 80% dioxane/water decrease in the order Cu(II) > (Zn(II). However, just the opposite behavior has been obtained for these metal complexes with the ligand in methanol (Zn(II) > (Cu(II)). The magnitudes of these ion association constants are related to the nature of solvation of the cation and of the complexed cation. The mobility of the complexes is also dependent, in part, upon solvation effects. Since the mobility of the VO(IV)L complex has been found to be higher than that of VO(IV) ion, assuming that the complex–solvent interaction in the VO(IV)‐L systems is comparatively weak. A major consequence of the complexation is the increase in the molar conductivity of the complex and a corresponding large decrease in κ values. For this reason, it was not obtained any stability constant values for VO(IV)‐L systems in two type of solvents.","PeriodicalId":22160,"journal":{"name":"Synthesis and Reactivity in Inorganic and Metal-organic Chemistry","volume":"28 1","pages":"819 - 831"},"PeriodicalIF":0.0,"publicationDate":"2004-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89445181","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on elemental analyses, molar conductivity and room‐temperature magnetic moment measurements, IR and electronic spectral studies, it is proposed that these complexes have extended IA‐bridged structures consisting of two iron(III) ions, each in a distorted octahedral environment. The complexes (1) and (2) were further characterized by variable‐temperature (4.2–300 K) magnetic susceptibility measurements and the observed data were successfully simulated by the equation based on the spin Hamiltonian operator, Ĥ = −2JŜ 1 Ŝ 2, giving the exchange parameter J = −9.21 cm−1 for (1) and J = −10.85 cm−1 for (2). These results are commensurate with weak antiferromagnetic spin‐exchange interaction between the two iron(III) ions within each molecule. The influence of halogen substituents in the bridging ligand on magnetic interactions between the metal ions of this kind of complexes is preliminarily discussed.","PeriodicalId":22160,"journal":{"name":"Synthesis and Reactivity in Inorganic and Metal-organic Chemistry","volume":"3 1","pages":"785 - 796"},"PeriodicalIF":0.0,"publicationDate":"2004-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87811520","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The binary complexes react with 8‐hydroxyquinoline (8‐HOqu) and oxalic acid (H2Ox) to form mixed‐ligand complexes. The mixed ligand complexes were prepared by using various molar ratios of LiOH. The thermal studies explored the stability of the mixed‐ligands in their complexes as the isolated thermal products also contain the mixed ligands. All of the binary and mixed‐ligand complexes have octahedral configurations except [CuHL]Cl and [ZnL], which have square‐planar geometrics. The Schiff base ligand (H2L) is coordinated to the central metal atom as a neutral, monoanionic and/or dianionic tetradentate ONNO ligand in the binary complexes and in the mixed‐ligand complexes. The mixed‐ligand, 8‐HOqu behaves as a neutral or monoanionic bidentate ligand. The oxalato ligand coordinates as a dianionic bidentate or a bridged bidentate ligand towards Fe(III) ions. All complexes and the corresponding thermal products were isolated and their structures were elucidated by elemental analyses, conductance, IR and electronic absorption spectra, magnetic moments, 1H NMR and TG‐DSC measurements as well as by mass spectroscopy.

The ligands were prepared by a two‐stage aldol condensation reaction in the molar ratio 1:1 of 2‐hydroxybenzaldehyde, 2′‐hydroxyacetophenone, or 2′,4′‐dihydroxyacetophenone and 1,2‐diaminopropane of the general formula HA x (x = 1–3) as precursors. The tetradentate mixed donor ligands of the general formula H2L x (x = 1–6) were obtained by condensation reaction of precursors with appropriate ketone or aldehyde. The synthesis of the ligand system, described here, is an efficient and easy method with the advantages of high yield, selectivity, and short reaction times. Only a brown polymeric form was obtained for VOL2 and green monomeric forms were obtained for VOL x , x = 1, 3–5, while in the presence of strong field ligands only monomeric forms were obtained. These observations suggest that monomeric forms of oxovanadium(IV) complexes exhibit a coordination number of five with N2O3 donor sets and the polymeric form exhibits a coordination number of six with N2O4 donor sets. Analytical data, 1H NMR, IR, UV–VIS spectra, and elemental analyses confirm the nature of the products.","PeriodicalId":22160,"journal":{"name":"Synthesis and Reactivity in Inorganic and Metal-organic Chemistry","volume":"133 1","pages":"611 - 626"},"PeriodicalIF":0.0,"publicationDate":"2004-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86475577","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
