Abstract

LLANOS, Jaime et al. A NEW STRUCTURAL MODIFICATION OF STANNITE. Bol. Soc. Chil. Quím. [online]. 2000, vol.45, n.4, pp.605-609. ISSN 0366-1644.  http://dx.doi.org/10.4067/S0366-16442000000400013.

The crystal structure of the phase a-SnCu2FeS4, has been examined by EDX and electron and X-ray difraction techniques. This compound crystallizes in the tetragonal space group P4 (No. 81) with a=c= 541.4 (4) pm, Z=1, and it is a derivative structure of the basic sphalerite structure. The refinement of the structure converged to the final agreement index R(F)=0.060.

Keywords : chalcogenides; electron diffraction; electron microscopy; X-ray diffraction.
