Resumo: | Triazenes and/or triazenido ligands, strategically substituted by terminal aryl groups [-N=NN(H)-] or (-N3 --) chains and containing halogen in the ortho position and ester in the para position, were evaluated in relation to the occurrence of intermolecular interactions through secondary non-covalent bonding. The research is based on the single crystal X-ray diffraction to analysis of arrangements performed by the free triazene molecules and by the triazenido complexes in the solid state. Triazenido ligands show a variety of modes of coordination which has motivated several structural studies of free triazenes and related complexes with diverse transition metals. This work report the synthesis and crystal structure of five new molecules in the literature: 1-(2-chlorophenyl)-3-(4-ethoxycarbonylphenyl)triazene; 1-(2-bromophenyl)-3-(4-ethoxycarbonylphenyl)triazene, and the mononuclear complexes bis[1-(4-ethoxycabonylphenyl)-3-(2-fluorophenyl)- triazenide]mercury(II), cis-bis[3-(2-fluorophenyl)-1-(4-carboxyphenyl)triazenide]-bis(pyridine)- nickel(II) and trans-bis[3-(2-iodophenyl)-1-(4-carboxyphenyl)triazenide]-bis(pyridine) copper(II). The asymmetric diaryltriazene molecules, Ar-NNNH-Ar [Ar = o-C6H4-X (X=F, Cl, Br, I); Ar = p-C6H4-CO2Et] and the related complexes were obtained in good yields in accordance with the reaction conditions of similar compounds reported in literarure. Beside the structural analysis of al compounds, melting-point, infrared, nuclear magnetic resonance and ultraviolet-visible espectroscopies wer also carried out for characterization. |

A investigação baseou-se principalmente na difração de raios-X em monocristal para analisar estruturalmente a formação de arranjos supramoleculares formados pelas moléculas e complexos no estado sólido. Ligantes triazenidos apresentam uma variedade de modos de coordenação os quais tem motivado vários estudos estruturais desses compostos nas moléculas livres e em complexos com metais de transição. Sob este ponto de vista, apresenta-se neste trabalho a síntese e a investigação da estrutura cristalina e molecular de cinco moléculas inéditas na literatura: os pré-ligantes 1-(2-clorofenil)-3-(4-etoxicarbonilfenil)triazeno; 1-(2-bromofenil)-3- (4-etoxicarbonilfenil)triazeno, e dos complexos mononucleares bis[1-(4-etoxicabonilfenil)-3-(2-fluorofenil)triazenido]mercúrio(II); cis-bis[3-(2-fluorofenil)-1-(4-etoxicarbonilfenil)triazenido]- bis (piridina)níquel(II) e trans-bis[3-(2-iodofenil)-1-(4-etoxicarbonilfenil)triazenido]-bis(piridina)cobre(II). Os ligantes bis(aril)triazenos, Ar-NNNH-Ar [Ar = o-C6H4-X (X=F, Cl, Br, I); Ar = p- C6H4-CO2Et] e os complexos foram preparados com bons rendimentos de acordo com condições padrões relatadas na literarura. Técnicas de ponto de fusão, espectroscopias de infravermelho, ressonância magnética nuclear e na região do ultravioleta-visível complementaram o trabalho.Coordenação de Aperfeiçoamento de Pessoal de Nível Superiorapplication/pdfporUniversidade Federal de Santa MariaPrograma de Pós-Graduação em QuímicaUFSMBRQuímicaTriazenoComplexos triazenidosDifração de raios-XArranjo supramolecularTriazeneTriazenide complexX-ray diffractionSupramolecular arrangementCNPQ::CIENCIAS EXATAS E DA TERRA::QUIMICASupramolecularidade de triazenos assimétricos dissubstituídos 4-(etoxicarbonilfenil)-2-(halofenil) e complexos de Ni(II), Cu(II) e Hg(II)Supramolecularity of asymmetric disubstituted 4-(ethoxycarbonylphenyl)-2-(halophenyl)triazenes and complexes containing Ni(II), Cu(II), and Hg(II)info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisHörner, Manfredohttp://lattes.cnpq.br/8922528250830998Nunes, Fabio Souzahttp://lattes.cnpq.br/7117607785614286Squizani, Fatimahttp://lattes.cnpq.br/1060502818943139http://lattes.cnpq.br/4916197985145809Broch, Fernanda1006000000004005005005005007e7796b1-053d-4bbe-8e62-e769f0da5ceaf1769b0d-0060-42c9-82c0-8819ed0e30f03694402e-84bf-43d1-a3a8-562172c526556c576d48-34e1-4008-b46b-a68350c55a17info:eu-repo/semantics/openAccessreponame:Biblioteca Digital de Teses e Dissertações do UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALFERNANDABROCH.pdfapplication/pdf3046348http://repositorio.ufsm.br/bitstream/1/10428/1/FERNANDABROCH.pdf64b96b1e115d53a9e5e2e8cb9b2fd15fMD51TEXTFERNANDABROCH.pdf.txtFERNANDABROCH.pdf.txtExtracted texttext/plain201505http://repositorio.ufsm.br/bitstream/1/10428/2/FERNANDABROCH.pdf.txt434d509dd249cdc54a62e12910dbc7c6MD52THUMBNAILFERNANDABROCH.pdf.jpgFERNANDABROCH.pdf.jpgIM Thumbnailimage/jpeg4908http://repositorio.ufsm.br/bitstream/1/10428/3/FERNANDABROCH.pdf.jpg93de82e2eb6f8b94ea288f88b9d66a9fMD531/104282023-04-17 14:18:14.564oai:repositorio.ufsm.br:1/10428Biblioteca Digital de Teses e Dissertaçõeshttps://repositorio.ufsm.br/ONGhttps://repositorio.ufsm.br/oai/requestatendimento.sib@ufsm.br||tedebc@gmail.comopendoar:2023-04-17T17:18:14Biblioteca Digital de Teses e Dissertações do UFSM - Universidade Federal de Santa Maria (UFSM)false |
