The dimeric tetraorganodicarboxylatodistannoxanes [(Me2SnL)2O]2 compound (2) and [(Bu2SnL)2O]2 compound (4), L = C15H10ClO2 −, were synthesized by the reaction of R2SnO with the ligand acid (HL) in 1:1 molar ratio with azeotropic removal of water. The structures of the complexes are discussed on the basis of IR, multinuclear (1H, 13C, 119Sn) NMR, 119mSn Mössbauer spectroscopies and mass spectrometry. The spectroscopic results substantiate that all the diorganotin(IV) derivatives possess trigonal‐bipyramidal structures in solution and octahedral geometry in the solid state. A linear polymeric trigonal‐bipyramidal structure in the solid state and a tetrahedral environment around the tin atom in non‐coordinating solvents has been proposed for the triorganotin(IV) derivatives. The Δν [Δν = νasym(COO) − νsym(COO)] values obtained from the IR data, in comparison to the ligand acid and its sodium salt, fall in the range which shows that the ligand may act as a bidentate coordinating group through the carboxyl (COO) oxygen atoms. The biological activity and LD50 data of the synthesized compounds are also reported. The triorganotin(IV) complexes exhibit significantly better activities than the diorganotin(IV) derivatives. The LD50 data show that most of the investigated compounds are cytotoxic.","PeriodicalId":22160,"journal":{"name":"Synthesis and Reactivity in Inorganic and Metal-organic Chemistry","volume":"2 1","pages":"1379 - 1399"},"PeriodicalIF":0.0,"publicationDate":"2004-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89697640","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 Cu(II) complex reacts with the ligands 1,10‐phenanthroline or 2‐aminopyridine to form mixed‐ligand complexes. All the binary complexes of Cd(II), Cu(II), and Ni(II) have octahedral configurations, while the Co(II) complex is square‐planar. The binary complexes of Th(IV) and UO2(VI) have distorted dodecahedral geometries. The mixed‐ligand complexes have octahedral configurations. Thermal studies on these complexes showed the possibility of obtaining new complexes pyrolytically, where the complexes decompose through several isolable as well as non‐isolable intermediates during heating. The structures of all complexes and the corresponding thermal products 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 ligand and some of the complexes were found to activate the enzyme pectinlyase.","PeriodicalId":22160,"journal":{"name":"Synthesis and Reactivity in Inorganic and Metal-organic Chemistry","volume":"12 1","pages":"1349 - 1378"},"PeriodicalIF":0.0,"publicationDate":"2004-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75233236","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}

It is proposed that these complexes have oxamido‐bridged structures consisting of planar copper(II) and octahedral manganese(II) ions. The electronic reflectance spectra indicate the presence of exchange–coupling interaction between bridging copper(II) and manganese(II) ions. The cryomagnetic measurements (4.2–300 K) of the three complexes demonstrated the operation of antiferromagnetic interaction between the adjacent manganese(II) and copper(II) ions through the oxamido‐bridge within these copper(II)–manganese(II) heterobinuclear complexes. On the basis of the spin Hamiltonian, Hˆ= − 2Sˆ1 · Sˆ2, a magnetic analysis was carried out for the three complexes and the spin‐coupling constant (J) was evaluated as −39.7 cm−1 for (1), −38.5 cm−1 for (2), and −37.8 cm−1 for (3). The influence of methyl substituents in amine groups of the bridging ligand on magnetic interactions between the metal ions of this kind of complexes is also discussed.","PeriodicalId":22160,"journal":{"name":"Synthesis and Reactivity in Inorganic and Metal-organic Chemistry","volume":"29 1","pages":"1165 - 1179"},"PeriodicalIF":0.0,"publicationDate":"2004-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90985177","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}
