Estudo molecular e supramolecular de complexos triazenidos com metais de transição: uma abordagem voltada à engenharia de cristais
(Universidade Federal de Santa Maria, 2017-09-15)
This work shows the synthesis of unpublished Zn(II), Cd(II) and Pd(II) complexes with
bis-cated triazene molecules, including macrocycles. Together these compounds, a series of
symmetrical ortho-halogenated single-catenad ...
Engenharia de cristais: estudo conformacional, topológico e energético de t-butilpirazóis e bis-t-butilpirazóis
(Universidade Federal de Santa Maria, 2019-02-22)
This work presents a proposed crystallization mechanism and conformational study of regioisomers of 5(3)-aryl-3(5)-carboxyethyl-1-(1,1-dimethylethyl)-1H-pyrazole (aryl, 4-X-C6H4, where X = H, F, Cl and Br) and a series of ...
Triazenos N-óxidos e seus complexos de Au(I) e Pd(II): uma abordagem no contexto da engenharia de cristais
(Universidade Federal de Santa Maria, 2018-02-02)
This work presents the synthesis of several molecular models, divided into four
chapters, and which were strategically synthesized for application in Crystal Engineering. In
the first chapter the synthesis of a series ...
Similaridade de estruturas supramoleculares em cristais orgânicos: proposta de índices quantitativos
(Universidade Federal de Santa Maria, 2018-06-20)
This investigation reports the proposal of a new method to obtain quantitative indexes of
similarity in crystals, using the supramolecular cluster as study demarcation. A series of
tert-butyl pyrazoles were used as models ...
