DELGADO, Gerzon E; GRIMA-GALLARDO, Pedro; QUINTERO, Miguel  e  CHACON, Cecilia. Preparation and structural characterization of the new diamond-like semiconductor CuMnInSe₃. Rev. Téc. Ing. Univ. Zulia [online]. 2018, vol.41, n.1, pp.25-31. ISSN 0254-0770.

The chalcogenide compound CuMnInSe₃, belonging to the system I-II-III-VI₃, has been investigated by means of X-ray powder diffraction and its crystal structure has been refined by the Rietveld method. The powder pattern was composed by 85.3% of the principal phase CuMnInSe₃ and 14.7% of the secondary phase MnSe. This material crystallizes with a CuFeInSe₃- type structure in the tetragonal space group P 2c (Nº 112), with unit cell parameters a = 5.7907(5) Å, c = 11.648(1) Å, V = 390.58(8) ų.

Palavras-chave : Chalcogenides; Semiconductors; Chemical synthesis; X-ray diffraction; Crystal structure.
