DELGADO, G.E.; GRIMA-GALLARDO, P.  e  QUINTERO, M.. Synthesis and crystal structure of three new quaternary compounds in the system (Cu-III-Se₂)_{1- x} ZnSe _x (III = Al, Ga, In), formed by Zn incorporation in Cu-III-Se₂ chalcopyrites. Rev. mex. fis. [online]. 2016, vol.62, n.4, pp.393-397. ISSN 0035-001X.

The crystal structure of the chalcogenide alloys CuZnAlSe3, CuZnGaSe3 and CuZnInSe3, new members of the system I-II-III-VI3, were characterized using X-ray powder diffraction data. All materials crystallize in the tetragonal space group P 4 2c (N° 112) with a CuFeInSe3-type structure.
