Resumo: | Uranyl complexes with ligands with oxygen and nitrogen donors have been extensively reviewed and they have aroused interest on account of their high stability, usefulness in selective chemical separations and their formation in higher coordination numbers, but quite a few complexes of hydrazone and semicarbazone ligands have been reported. This fact was the inspiration to the search of the synthesis and characterization of new uranium complexes with hydrazones, semicarbazones and related ligands in intention to explore the reactivity and coordination behavior of the uranium, as well to understand the interactions between the metal center with these ligands. The structural study in the solid state for the characterization of the interactions in the crystalline structures of the uranium compounds synthesized was carried out with single crystal X-ray diffraction. In this way, the relation between crystalline structure and supramolecular organization could be better understood. It was characterized with single crystal X-ray diffraction 2 hydrazones and also 19 new uranium complexes. Many metallic complexes had been found as monomers, dimers, trimers and until tetramer, what it demonstrates the versatility and the geometry of coordination of the uranium atom and the ligands used in the formation of these complexes. The hydrogen bonds also play an important role in the crystallization and stabilization of the three-dimensional structures. There are intra and intermoleculares interactions between ligands molecules, solvent group and uranyl oxo ligands, however the hydrogen-bonding interactions have no influence in the coordination of the metal atom. The uranium atoms in the complexes present high coordination numbers and a polyhedron of coordination as a pentagonal bipyramid and/or hexagonal bipyramid. |

Esse fato levou a investigação da síntese e caracterização de novos complexos de urânio com hidrazonas, semicarbazonas e ligantes relacionados, no intuito de explorar a reatividade e o comportamento coordenativo do urânio, bem como compreender as interações entre o centro metálico e esses ligantes. Efetuou-se um estudo estrutural no estado sólido para a caracterização das interações presentes nas estruturas cristalinas dos compostos de urânio sintetizados e a ferramenta mais utilizada foi a difração de raios X. Desta forma, aprofundou-se a compreensão da relação entre a estrutura cristalina dos complexos de urânio e sua organização supramolecular. Foram caracterizadas 2 hidrazonas por difração de raios X e um total de 19 novos complexos de urânio. Muitos complexos metálicos foram encontrados como monômeros, dímeros, trímeros e até tetrâmeros, o que demonstra a versatilidade no modo e na geometria de coordenação do átomo de urânio e dos ligantes utilizados na formação destes complexos. As ligações de hidrogênio também tiveram um papel importante na cristalização do empacotamento cristalino tridimensional, existindo ligações intra e intermoleculares entre as moléculas dos ligantes, moléculas de solventes e o grupo oxo da uranila. Entretanto, observa-se que essas interações não influenciaram na coordenação do átomo do metal. Os átomos de urânio nos complexos obtidos apresentam elevados números de coordenação e um poliedro de coordenação na forma de um bipiramide pentagonal e/ou bipiramide hexagonal.application/pdfporUniversidade Federal de Santa MariaPrograma de Pós-Graduação em QuímicaUFSMBRQuímicaQuímicaComplexo de urânioQuímica orgânicaCNPQ::CIENCIAS EXATAS E DA TERRA::QUIMICASíntese e análise estrutural de complexos de urânio(VI) com hidrazonas, semicarbazonas e ligantes relacionadosSynthesis and structural analysis of uranium(VI) complexes with hydrazones, semicabazones and related ligands.info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesisLang, Ernesto Schulzhttp://lattes.cnpq.br/4481982189769819Burrow, Robert Alanhttp://lattes.cnpq.br/5452385625669684Soares, Jaísa Fernandeshttp://lattes.cnpq.br/6393567108244426Deflon, Victor Marcelohttp://lattes.cnpq.br/8068967021078220Fenner, Hertonhttp://lattes.cnpq.br/2943736272592164http://lattes.cnpq.br/0533357429795905Gatto, Claudia Cristina1006000000004003003003003003003000c9d7568-d5c4-466d-b807-0125a7d37b97f93a642a-629e-4860-9d43-3e09b6ad926a803cc95d-eb6b-4016-8139-33ad0459ad5c2bb2b796-bef3-4621-b286-706256e8656973f14e64-676e-476d-a31e-5639a5a50deac032f384-d82f-4f78-a069-dcf4471c7f5dinfo:eu-repo/semantics/openAccessreponame:Biblioteca Digital de Teses e Dissertações do UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALCLAUDIAGATTO1.pdfapplication/pdf9856516http://repositorio.ufsm.br/bitstream/1/4140/1/CLAUDIAGATTO1.pdf2cc71ee193852a770b80a1a3c1aa405cMD51CLAUDIAGATTO2.pdfCLAUDIAGATTO2.pdfapplication/pdf9200221http://repositorio.ufsm.br/bitstream/1/4140/4/CLAUDIAGATTO2.pdf7e73c62499d86731e189c5fc4397c726MD54CLAUDIAGATTO3.pdfCLAUDIAGATTO3.pdfapplication/pdf14046614http://repositorio.ufsm.br/bitstream/1/4140/5/CLAUDIAGATTO3.pdfcb4b4a97f6f589dd0210c394c4786978MD55CLAUDIAGATTO4.pdfCLAUDIAGATTO4.pdfapplication/pdf11874263http://repositorio.ufsm.br/bitstream/1/4140/6/CLAUDIAGATTO4.pdfe074d316690cddbf0553b4ed8899ce1eMD56CLAUDIAGATTO5.pdfCLAUDIAGATTO5.pdfapplication/pdf1401536http://repositorio.ufsm.br/bitstream/1/4140/7/CLAUDIAGATTO5.pdf64c9c55540eb0338519f3b176dc0ae69MD57TEXTCLAUDIAGATTO1.pdf.txtCLAUDIAGATTO1.pdf.txtExtracted texttext/plain75641http://repositorio.ufsm.br/bitstream/1/4140/2/CLAUDIAGATTO1.pdf.txtadab4f1989d0915cd8de2cf77563dc01MD52CLAUDIAGATTO2.pdf.txtCLAUDIAGATTO2.pdf.txtExtracted texttext/plain50451http://repositorio.ufsm.br/bitstream/1/4140/8/CLAUDIAGATTO2.pdf.txt1474e8581f66e7d0d82431d3bae1f5dcMD58CLAUDIAGATTO3.pdf.txtCLAUDIAGATTO3.pdf.txtExtracted texttext/plain46408http://repositorio.ufsm.br/bitstream/1/4140/10/CLAUDIAGATTO3.pdf.txt98ec2020014659eec10ac9ae1b54d101MD510CLAUDIAGATTO4.pdf.txtCLAUDIAGATTO4.pdf.txtExtracted texttext/plain47500http://repositorio.ufsm.br/bitstream/1/4140/12/CLAUDIAGATTO4.pdf.txtec2a45110977fbd8870faa0b5c1e5d4bMD512CLAUDIAGATTO5.pdf.txtCLAUDIAGATTO5.pdf.txtExtracted texttext/plain191929http://repositorio.ufsm.br/bitstream/1/4140/14/CLAUDIAGATTO5.pdf.txt97f80609115dff784d984d837d4b4db4MD514THUMBNAILCLAUDIAGATTO1.pdf.jpgCLAUDIAGATTO1.pdf.jpgIM Thumbnailimage/jpeg4775http://repositorio.ufsm.br/bitstream/1/4140/3/CLAUDIAGATTO1.pdf.jpg58bb3666411268dca1e5a7adeed6767eMD53CLAUDIAGATTO2.pdf.jpgCLAUDIAGATTO2.pdf.jpgIM Thumbnailimage/jpeg4138http://repositorio.ufsm.br/bitstream/1/4140/9/CLAUDIAGATTO2.pdf.jpgb007001822fa186c4349346ba629269eMD59CLAUDIAGATTO3.pdf.jpgCLAUDIAGATTO3.pdf.jpgIM Thumbnailimage/jpeg8347http://repositorio.ufsm.br/bitstream/1/4140/11/CLAUDIAGATTO3.pdf.jpg6b27a09cabb53ce06e821557ef2514a4MD511CLAUDIAGATTO4.pdf.jpgCLAUDIAGATTO4.pdf.jpgIM Thumbnailimage/jpeg6917http://repositorio.ufsm.br/bitstream/1/4140/13/CLAUDIAGATTO4.pdf.jpg13052e756eb83a71b8fcd1e480f455c3MD513CLAUDIAGATTO5.pdf.jpgCLAUDIAGATTO5.pdf.jpgIM Thumbnailimage/jpeg2190http://repositorio.ufsm.br/bitstream/1/4140/15/CLAUDIAGATTO5.pdf.jpg61ebae0152fd256b864081cda29c61ceMD5151/41402023-01-09 09:51:18.893oai:repositorio.ufsm.br:1/4140Biblioteca Digital de Teses e Dissertaçõeshttps://repositorio.ufsm.br/ONGhttps://repositorio.ufsm.br/oai/requestatendimento.sib@ufsm.br||tedebc@gmail.comopendoar:2023-01-09T12:51:18Biblioteca Digital de Teses e Dissertações do UFSM - Universidade Federal de Santa Maria (UFSM)false |
