Revista Processos Químicos, Goiânia, v. 4, n. 7, p. 19-32, jan./jun. 2010.1981-8521http://repositorio.bc.ufg.br/handle/ri/15261In order to know the molecular and crystalline structure of chemical compounds for further physical-chemical analysis and application studies, launches hand of crystallography as a scientific methodology that allows knowing the structure of any crystalline chemical compound without any a priori information. This methodology is based on concepts such as X-ray diffraction by crystalline materials, symmetry, Bragg’s law and Fourier transform. This work aims to present the main steps of crystallographic methodology, since the data collection from a single crystal, solution and refinement of structures until the steps of analysis and validation of crystallographic model, and deposit in appropriate crystallographic database.porAcesso AbertoEstrutura molecularDifração de raios XInterações intermolecularesMolecular structureX-ray diffractionIntermolecular interactionsArtigo
