DELGADO, G.E.  and  SAGREDO, V.. Synthesis and crystal structure of the quaternary semiconductor Cu₂NiGeS₄, a new stannite-type compound. Rev. mex. fis. [online]. 2019, vol.65, n.4, pp.355-359.  Epub May 06, 2020. ISSN 0035-001X.  https://doi.org/10.31349/revmexfis.65.355.

The crystal structure of the quaternary compound Cu2NiGeS4, belonging to the system I2-II-IV-VI4, was characterized by Rietveld refinement using X-ray powder diffraction data. This material crystallizes with a stannite structure in the tetragonal space group I42m (N°121), Z = 2, unit cell parameters a = 5.3384 (1) Å, c = 10.5732 (3) Å, V = 301.32 (3) Å3, acknowledged as a normal valence adamantane-structure.
