Estudo teórico sobre o efeito de substituintes na interação cátion- em rutenofanos

Garcia, Leone Carmo January 2013 (has links)
Dissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Ciências Físicas e Matemáticas, Programa de Pós-Graduação em Química, Florianópolis, 2013 / Made available in DSpace on 2013-07-16T21:10:24Z (GMT). No. of bitstreams: 1 316877.pdf: 6249192 bytes, checksum: 8d85c008bedb049f65bf8c3955feb90f (MD5) / Estudou-se, através de métodos de química teórica, o efeito do substituinte na interação cátion-? em rutenofanos. Para isto investigou-se a estrutura eletrônica de uma série de nove complexos de fórmula geral [Ru(NH3)3(?6-C16H12R4)]2+: 1 (R1=R2=R3=R4=H), 2 (R1=R2=R3=R4=F), 3 (R1=R2=R3=R4=Cl), 4 (R1=R2=R3=R4=CN), 5 (R1=R2=R3=R4=CH3), 6 (R1=R4=NO2 e R2=R3=H), 7 (R1=R4=NH2 e R2=R3=H), 8 (R1=R4=OCH3 e R2=R3=H), 9 (R1=R2=R3=R4=H e carbono ipso protonado). A magnitude da interação cátion-? foi avaliada, bem como decomposta em suas diferentes componentes por meio da análise da decomposição de energia proposta por Su-Li no nível de teoria MP2/def2-TZVP. Observou-se que tais interações são principalmente covalentes em sua natureza, ao passo que a contribuição eletrostática é bastante significativa, sendo que os substituintes retiradores de elétrons enfraquecem a interação, já os doadores fortalecem as mesmas. Informações adicionais foram obtidas por meio de análises NBO, as quais revelam que as retrodoações, em especial aquelas do tipo 4d ? 2pz, são mais importantes sob uma perspectiva energética. Um estudo topológico sob a luz da teoria QTAIM sugere que as interações cátion-? nos rutenofanos estudados são consistentes com interações de camada fechada com propriedades que apontam para ligações coordenadas.
