MARROQUIN, Gustavo; DELGADO, Gerzon E.; GRIMA-GALLARDO, Pedro y QUINTERO, Miguel. Preparation, differential thermal analysis and crystal structure of the new quaternary compound CuVInSe3. Rev. mex. fis. [online]. 2018, vol.64, n.6, pp.548-552. Epub 05-Nov-2019. ISSN 0035-001X. https://doi.org/10.31349/revmexfis.64.548.
The crystal structure of the quaternary compound CuVInSe , belonging to the system (CuInSe ) (VSe) with , was analyzed using X-ray powder diffraction data. This material was synthesized by the melt and anneal method and crystallizes in the tetragonal space group P 2c (N 112), with unit cell parameters Å, Å, Å. The Rietveld refinement of 25 instrumental and structural variables led to %, %, % and for 4501 step intensities, and 153 independent reflections. This compound has a normal adamantane structure and is isostructural with CuFeInSe . The DTA indicates that this compound melts at 1332 K.
