GONZALEZ R, O; RIVAS V, K  e  GONZALEZ M, V. Propiedades estructurales de algunos compuestos de intercalación de grafito. Rev. mex. fis. [online]. 2006, vol.52, suppl.3, pp.178-180. ISSN 0035-001X.

Novel graphite bi-intercalation compounds (GBICs) with layers of ErCl₃ and HoCl₃ were synthesized by sequential intercalation, using one-zone vapour phase method from well defined stage-2 GdCl₃ and SmCl₃ binary graphite intercalation compounds as host matrices. The x-ray diffraction shows stage-2 new compounds with c-axis repeat distances similar to those of the host matrices, which indicates that second intercalate layers are located into the same galleries. The electron diffraction also shows commensurate and incommensurate structures on both compounds.

Palavras-chave : Graphite; bi-intercalation; diffraction.
