Resumo: | The synthesis and structural analysis of three new coordination compounds containing uranium metal are described in this dissertation. These compositions were synthesized with a mimetic ligand to a biological structure, well with a ligand of biological function described in the literature. The compound (UO2)(Pyridoxine Hydrocloride)2(H2O) was synthesized by the reaction of pyridoxine, uranyl nitrate and triethylamine in acetonitrile. After 3 weeks darkness orange crystals were obtained. It was verified that these crystals belonged to the triclinic system, space group P¯1 , the constants of cell are: a = 7.5298(5) Å, b = 8.9828(7) Å, c =16.7710(12) Å, α = 75.2930(10) Å, β = 89.249(2) Å, γ = 80.5320(10) Å. The X-ray diffraction demonstrates that in this complex the uranium atom is in the form of a uranyl moiety (UO2) and coordinates with two molecules of the bidentate ligand pyridoxine and a water molecule, to form a pentagonal bipyramidal coordenation geometry. The compound [(UO2)(4-Phenil-Semicarbazid)3](NO3)2 was obtained by the reaction of the uranyl nitrate and 4-phenil-semicarbazid in acetonitrile. Yellows crystals of cubic habit were obtained after two days. The structural analysis revealed that these crystals belong to the monoclinic system, space group P21/c. The cell constants found were a = 12.618(3) Å, b = 16.810(17) Å, c = 15.189(2), β = 93.23(2)°. The coordination geometry found for the uranium atom is hexagonal bipyramidal. In addition to the two uranyl oxigen atoms bound to the metal (UO2), three molecules of the bidentate ligand 4- phenil-semicarbazid coordenate to the uranium center. The compound [(UO2) 2-(2´-Hydroxyphenyl) Benzoxazole)2(MeOH)] was obtained by the reaction of 2-(2´-hydroxyphenil) benzoxazole and uranyl nitrate in methanol. Red and prismatic crystals formed. The crystalline system of this compound is monoclinic in the space group P21/c, the ceel constants are: a = 13.477(3) Å, b = 19.344(4) Å, c = 9.3029(19) Å, β = 92.306(5) Å. The pentagonal bipyramidal coordination geometry of this compound is make up whit two molecules of the bidentate ligand and one molecule of methanol coordenating to the uranyl grup (UO2). |

Estes compostos foram sintetizados com ligantes miméticos a estruturas biológicas, bem como um ligante de função biológica descrito na literatura. O composto [(UO2) (Hidrocloreto de Piridoxina)2(H2O)] foi sintetizado a partir da reação entre a piridoxina, nitrato de uranila e trietilamina em acetonitrila. Após 3 semanas foram obtidos cristais de coloração laranja escuro. Verificou-se que estes cristais pertenciam ao sistema triclínico, grupo espacial P¯1 ,com as constantes de cela iguais a: a = 7,5298(5) Å, b = 8,9828(7) Å, c =16,7710(12) Å, α =75,2930(10)°, β = 89,249(2)°, γ = 80,5320(10)°. A difração de raios X demonstra que neste complexo o átomo de urânio se apresenta na forma de um grupamento uranila (UO2) e coordena ainda com duas moléculas do ligante bidentado piridoxina e uma molécula de água, perfazendo uma geometria bipiramidal pentagonal. O composto [(UO2)(4-Fenil-Semicarbazida)3](NO3)2 foi obtido pela reação entre o nitrato de uranila e a 4-fenil-semicarbazida em acetonitrila. Os cristais de hábito cúbico e de coloração amarela foram obtidos após dois dias. A análise estrutural revelou que estes cristais pertenciam ao sistema monoclínico, grupo espacial P21/c. As constantes de cela encontradas foram a = 12,618(3) Å, b = 16,8101(17) Å, c = 15,189(2) Å, β = 93,23(2)°. A geometria de coordenação encontrada para o átomo de urânio é a bipiramidal hexagonal, pois, além das ligações dos átomos de oxigênio ao metal (UO2) outras três moléculas do ligante bidentado 4-fenil-semicarbazida coordenam ao urânio. O composto [(UO2) 2-(2´-Hidroxifenil) Benzoxazola)2(MeOH)] foi obtido pela reação entre a 2-(2´-hidroxifenil) benzoxazola e o nitrato de uranila em metanol. Os cristais apresentam-se sob coloração vermelha e de hábito prismático. O sistema cristalino deste composto é o monoclínico e o grupo espacial P21/c, tendo constantes de cela iguais a: a = 13,477(3) Å, b = 19,344(4) Å, c = 9,3029(19) Å, β = 92,306(5)°. A geometria de coordenação do átomo de urânio é bipiramidal pentagonal, pois além das ligações com dois átomos de oxigênio (UO2) ocorrem ligações entre duas moléculas do ligante bidentado, e uma ligação com uma molécula de metanol.porUniversidade Federal de Santa MariaCentro de Ciências Naturais e ExatasPrograma de Pós-Graduação em QuímicaUFSMBrasilQuímicaAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/openAccessAnálise estruturalSíntese químicaUrânioQuímica inorgânicaCNPQ::CIENCIAS EXATAS E DA TERRA::QUIMICASíntese e análise estrutural de complexos de urânio (VI) coordenados aos ligantes hidrocloreto de piridoxina, 4-fenil-semicarbazida e a 2-(2´-hidroxifenil) benzoxazola.Synthesis and structural analysis of uranium (VI) complexes cordenated whit ligand pyridoxine hydrochloride, 4-phenil-semicarbazid and the 2-(2´-hydroxyphenil) benzoxazoleinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisLang, Ernesto Schulzhttp://lattes.cnpq.br/4481982189769819Fenner, HertonPeixoto, Carlos Roberto de Menezeshttp://lattes.cnpq.br/3778138554788107Back, Davi Fernando1006000000006006006006006000c9d7568-d5c4-466d-b807-0125a7d37b972e5ec388-2a7d-487c-88f4-b177eef4e277374bc251-12cc-4196-b6f8-29c1de4bda1c5f9b9817-75bb-4393-af04-586a2f09f167reponame:Biblioteca Digital de Teses e Dissertações do UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMCC-LICENSElicense_rdflicense_rdfapplication/rdf+xml; charset=utf-8805http://repositorio.ufsm.br/bitstream/1/26768/2/license_rdf4460e5956bc1d1639be9ae6146a50347MD52ORIGINALDIS_PPGQUÍMICA_2004_BACK_DAVI.pdfDIS_PPGQUÍMICA_2004_BACK_DAVI.pdfDissertação de Mestradoapplication/pdf2250085http://repositorio.ufsm.br/bitstream/1/26768/1/DIS_PPGQU%c3%8dMICA_2004_BACK_DAVI.pdf5cc3e03b972377e75a0a5b2433469dc3MD51LICENSElicense.txtlicense.txttext/plain; charset=utf-81956http://repositorio.ufsm.br/bitstream/1/26768/3/license.txt2f0571ecee68693bd5cd3f17c1e075dfMD531/267682022-11-04 16:40:44.517oai:repositorio.ufsm.br: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 Digital de Teses e Dissertaçõeshttps://repositorio.ufsm.br/ONGhttps://repositorio.ufsm.br/oai/requestatendimento.sib@ufsm.br||tedebc@gmail.comopendoar:2022-11-04T19:40:44Biblioteca Digital de Teses e Dissertações do UFSM - Universidade Federal de Santa Maria (UFSM)false |
